INTRODUCTION TO OBJECT ORIENTED PROGRAMMING IN PHP

PHP What is OOP?

OOP stands for Object-Oriented Programming.

Procedural programming is about writing procedures or functions that perform operations on the data, while object-oriented programming is about creating objects that contain both data and functions.

Object-oriented programming has several advantages over procedural programming:

 OOP is faster and easier to execute  OOP provides a clear structure for the programs  OOP helps to keep the PHP code DRY "Don't Repeat Yourself", and makes the code easier to maintain, modify and debug  OOP makes it possible to create full reusable applications with less code and shorter development time

Define a Class

A class is defined by using the class keyword, followed by the name of the class and a pair of curly braces ({}). All its properties and methods go inside the braces:

Below we declare a class named Fruit consisting of two properties ($name and $color) and two methods set_name() and get_name() for setting and getting the $name property:

// Properties

public $name;

public $color;

// Methods

function set_name($name) {

$this->name = $name;

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

}

function get_name() {

return $this->name;

}

}

?>

Define Objects

Classes are nothing without objects! We can create multiple objects from a class. Each object has all the properties and methods defined in the class, but they will have different property values.

Objects of a class is created using the new keyword.

In the example below, $apple and $banana are instances of the class Fruit:

public $name;

public $color;

// Methods

function set_name($name) {

$this->name = $name;

}

function get_name() {

return $this->name;

}

}

$apple = new Fruit();

$banana = new Fruit();

$apple->set_name('Apple');

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

$banana->set_name('Banana');

echo $apple->get_name(); echo "
"; echo $banana->get_name();

?>

In the example below, we add two more methods to class Fruit, for setting and getting the $color property:

// Properties

public $name;

public $color;

// Methods

function set_name($name) {

$this->name = $name;

}

function get_name() {

return $this->name;

}

function set_color($color) {

$this->color = $color;

}

function get_color() {

return $this->color;

}

}

$apple = new Fruit();

$apple->set_name('Apple');

$apple->set_color('Red'); echo "Name: " . $apple->get_name(); echo "
"; echo "Color: " . $apple->get_color();

?>

PHP - The $this Keyword

The $this keyword refers to the current object, and is only available inside methods.

Look at the following example:

So, where can we change the value of the $name property? There are two ways:

1. Inside the class (by adding a set_name() method and use $this):

2. Outside the class (by directly changing the property value):

}

}

$apple = new Fruit();

?>

public $name;

}

$apple = new Fruit();

$apple->name = "Apple";

?>

PHP - instanceof

You can use the instanceof keyword to check if an object belongs to a specific class:

PHP OOP - Constructor

PHP - The __construct Function

A constructor allows you to initialize an object's properties upon creation of the object.

If you create a __construct() function, PHP will automatically call this function when you create an object from a class.

Notice that the construct function starts with two underscores (__)!

We see in the example below, that using a constructor saves us from calling the set_name() method which reduces the amount of code:

public $name;

public $color;

function __construct($name) {

$this->name = $name;

}

$apple = new Fruit("Apple"); echo $apple->get_name();

?>

public $color;

function __construct($name, $color) {

$this->name = $name;

$this->color = $color;

}

function get_name() {

return $this->name;

}

function get_color() {

return $this->color;

}

}

$apple = new Fruit("Apple", "red"); echo $apple->get_name(); echo "
"; echo $apple->get_color();

PHP - The __destruct Function

A destructor is called when the object is destructed or the script is stopped or exited.

If you create a __destruct() function, PHP will automatically call this function at the end of the script.

Notice that the destruct function starts with two underscores (__)!

The example below has a __construct() function that is automatically called when you create an object from a class, and a __destruct() function that is automatically called at the end of the script:

public $name;

}

function __destruct() {

}

}

PHP - Access Modifiers

Properties and methods can have access modifiers which control where they can be accessed.

There are three access modifiers:

 public - the property or method can be accessed from everywhere. This is default  protected - the property or method can be accessed within the class and by classes derived from that class  private - the property or method can ONLY be accessed within the class

In the following example we have added three different access modifiers to the three properties. Here, if you try to set the name property it will work fine (because the name property is public). However, if you try to set the color or weight property it will result in a fatal error (because the color and weight property are protected and private):

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

public $name;

protected $color;

private $weight;

}

$mango = new Fruit();

$mango->name = 'Mango'; // OK

$mango->color = 'Yellow'; // ERROR

$mango->weight = '300'; // ERROR

?>

In the next example we have added access modifiers to two methods. Here, if you try to call the set_color() or the set_weight() function it will result in a fatal error (because the two functions are considered protected and private), even if all the properties are public:

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

public $name;

public $color;

public $weight;

function set_name($n) { // a public function (default)

$this->name = $n;

}

protected function set_color($n) { // a protected function

$this->color = $n;

}

private function set_weight($n) { // a private function

$this->weight = $n;

}

}

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

$mango = new Fruit();

$mango->set_name('Mango'); // OK

$mango->set_color('Yellow'); // ERROR

$mango->set_weight('300'); // ERROR

?>

PHP - What is Inheritance?

Inheritance in OOP = When a class derives from another class.

The child class will inherit all the public and protected properties and methods from the parent class. In addition, it can have its own properties and methods.

An inherited class is defined by using the extends keyword.

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

public $name;

public $color;

public function __construct($name, $color) {

$this->name = $name;

$this->color = $color;

}

public function intro() {

echo "The fruit is {$this->name} and the color is {$this->color}.";

}

}

// Strawberry is inherited from Fruit class Strawberry extends Fruit {

public function message() {

echo "Am I a fruit or a berry? ";

}

}

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

$strawberry = new Strawberry("Strawberry", "red");

$strawberry->message();

$strawberry->intro();

?>

PHP - Inheritance and the Protected Access Modifier

In the previous chapter we learned that protected properties or methods can be accessed within the class and by classes derived from that class. What does that mean?

Let's look at an example:

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

public $name;

public $color;

public function __construct($name, $color) {

$this->name = $name;

$this->color = $color;

}

protected function intro() {

echo "The fruit is {$this->name} and the color is {$this->color}.";

}

}

class Strawberry extends Fruit {

public function message() {

echo "Am I a fruit or a berry? ";

}

}

// Try to call all three methods from outside class

$strawberry = new Strawberry("Strawberry", "red"); // OK. __construct() is public

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

$strawberry->message(); // OK. message() is public

$strawberry->intro(); // ERROR. intro() is protected

?>

In the example above we see that if we try to call a protected method (intro()) from outside the class, we will receive an error. public methods will work fine!

Let's look at another example:

public $name;

public $color;

public function __construct($name, $color) {

$this->name = $name;

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

$this->color = $color;

}

protected function intro() {

echo "The fruit is {$this->name} and the color is {$this->color}.";

}

}

class Strawberry extends Fruit {

public function message() {

echo "Am I a fruit or a berry? ";

// Call protected function from within derived class - OK

$this -> intro();

}

}

$strawberry = new Strawberry("Strawberry", "red"); // OK. __construct() is public

$strawberry->message(); // OK. message() is public and it calls intro() (which is protected) from within the derived class

?>

PHP - Overriding Inherited Methods

Inherited methods can be overridden by redefining the methods (use the same name) in the child class.

Look at the example below. The __construct() and intro() methods in the child class (Strawberry) will override the __construct() and intro() methods in the parent class (Fruit):

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

public $name;

public $color;

public function __construct($name, $color) {

$this->name = $name;

$this->color = $color;

}

public function intro() {

echo "The fruit is {$this->name} and the color is {$this->color}.";

}

}

class Strawberry extends Fruit {

public $weight;

public function __construct($name, $color, $weight) {

$this->name = $name;

$this->color = $color;

$this->weight = $weight;

}

public function intro() {

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

echo "The fruit is {$this->name}, the color is {$this->color}, and the weight is {$this->weight} gram.";

}

}

$strawberry = new Strawberry("Strawberry", "red", 50);

$strawberry->intro();

?>

PHP - The final Keyword

The final keyword can be used to prevent class inheritance or to prevent method overriding.

The following example shows how to prevent class inheritance:

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

class Strawberry extends Fruit {

}

?>

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

class Fruit {

final public function intro() {

}

}

class Strawberry extends Fruit {

// will result in error

public function intro() {

}

}

?>

PHP - Class Constants

Constants cannot be changed once it is declared.

Class constants can be useful if you need to define some constant data within a class.

A class constant is declared inside a class with the const keyword.

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

Class constants are case-sensitive. However, it is recommended to name the constants in all uppercase letters.

We can access a constant from outside the class by using the class name followed by the scope resolution operator (::) followed by the constant name, like here:

const LEAVING_MESSAGE = "Thank you for visiting W3Schools.com!";

}

echo Goodbye::LEAVING_MESSAGE;

?>

$goodbye->byebye();

PHP - What are Abstract Classes and Methods?

Abstract classes and methods are when the parent class has a named method, but need its child class(es) to fill out the tasks.

An abstract class is a class that contains at least one abstract method. An abstract method is a method that is declared, but not implemented in the code.

An abstract class or method is defined with the abstract keyword:

Syntax

When inheriting from an abstract class, the child class method must be defined with the same name, and the same or a less restricted access modifier. So, if the abstract method is defined as protected, the child class method must be defined as either protected or public, but not private. Also, the type and number of required arguments must be the same. However, the child classes may have optional arguments in addition.

So, when a child class is inherited from an abstract class, we have the following rules:

 The child class method must be defined with the same name and it redeclares the parent abstract method  The child class method must be defined with the same or a less restricted access modifier

PROF. YOGESH DESHMUKH www.dacc.edu.in

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

 The number of required arguments must be the same. However, the child class may have optional arguments in addition

Let's look at an example:

// Parent class abstract class Car {

public $name;

public function __construct($name) {

$this->name = $name;

}

abstract public function intro() : string;

}

// Child classes class Audi extends Car {

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

public function intro() : string {

return "Choose German quality! I'm an $this->name!";

}

}

class Volvo extends Car {

public function intro() : string {

return "Proud to be Swedish! I'm a $this->name!";

}

}

class Citroen extends Car {

public function intro() : string {

return "French extravagance! I'm a $this->name!";

}

}

// Create objects from the child classes

$audi = new audi("Audi");

PROF. YOGESH DESHMUKH www.dacc.edu.in

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

echo $audi->intro(); echo "
";

$volvo = new volvo("Volvo"); echo $volvo->intro(); echo "
";

$citroen = new citroen("Citroen"); echo $citroen->intro();

?>

Example Explained

The Audi, Volvo, and Citroen classes are inherited from the Car class. This means that the Audi, Volvo, and Citroen classes can use the public $name property as well as the public __construct() method from the Car class because of inheritance.

But, intro() is an abstract method that should be defined in all the child classes and they should return a string.

PHP - What are Interfaces?

Interfaces allow you to specify what methods a class should implement.

Interfaces make it easy to use a variety of different classes in the same way. When one or more classes use the same interface, it is referred to as "polymorphism".

Interfaces are declared with the interface keyword:

Syntax

PHP - Interfaces vs. Abstract Classes

Interface are similar to abstract classes. The difference between interfaces and abstract classes are:

 Interfaces cannot have properties, while abstract classes can  All interface methods must be public, while abstract class methods is public or protected  All methods in an interface are abstract, so they cannot be implemented in code and the abstract keyword is not necessary  Classes can implement an interface while inheriting from another class at the same time

DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45

Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA)

PHP - Using Interface implements keyword is used in interface .

To implement an interface, a class must use the implements keyword.

A class that implements an interface must implement all of the interface's methods.

public function makeSound();

}

class Cat implements Animal {

public function makeSound() {

echo "Meow";

}

}

$animal = new Cat();

$animal->makeSound();

?>

From the example above, let's say that we would like to write software which manages a group of animals. There are actions that all of the animals can do, but each animal does it in its own way.

Using interfaces, we can write some code which can work for all of the animals even if each animal behaves differently:

PHP - What are Traits?

PHP only supports single inheritance: a child class can inherit only from one single parent.

So, what if a class needs to inherit multiple behaviors? OOP traits is used to solve this problem.

Traits are used to declare methods that can be used in multiple classes. Traits can have methods and abstract methods that can be used in multiple classes, and the methods can have any access modifier (public, private, or protected).

Traits are declared with the trait keyword:

Syntax

To use a trait in a class, use the use keyword:

PHP - Static Methods

Static methods can be called directly - without creating an instance of the class first.

Static methods are declared with the static keyword:

Syntax

To access a static method use the class name, double colon (::), and the method name:

PHP - More on Static Methods

A class can have both static and non-static methods. A static method can be accessed from a method in the same class using the self keyword and double colon (::):

public static function welcome() {

echo "Hello World!";

}

public function __construct() {

self::welcome();

}

}

An iterable is any value which can be looped through with a foreach() loop.

The iterable pseudo-type was introduced in PHP 7.1, and it can be used as a data type for function arguments and function return values.

PHP - Using Iterables

The iterable keyword can be used as a data type of a function argument or as the return type of a function:

foreach($myIterable as $item) {

echo $item;

}

}

$arr = ["a", "b", "c"]; printIterable($arr);

?>

PHP Namespaces

Namespaces are qualifiers that solve two different problems:

1. They allow for better organization by grouping classes that work together to perform a task 2. They allow the same name to be used for more than one class

For example, you may have a set of classes which describe an HTML table, such as Table, Row and Cell while also having another set of classes to describe furniture, such as Table, Chair and Bed. Namespaces can be used to organize the classes into two different groups while also preventing the two classes Table and Table from being mixed up.

Declaring a Namespace

Namespaces are declared at the beginning of a file using the namespace keyword:

$_SERVER is a superglobal that holds information regarding HTTP headers, path and script location etc. All the server and execution environment related information is available in this associative array. Most of the entries in this array are populated by web server. PHP versions prior to 5.4.0 contained $HTTP_SERVER_VARS contained same information but has now been removed. Following are some prominent members of this array PHP_SELF − stores filename of currently executing script. For example, a script in test folder of document root of a local server returns its path as follows − Example

echo $_SERVER['PHP_SELF'];

?>

This results in following output in browser with http://localhost/test/testscript.php URL

/test/testscript.php SERVER_ADDR − This property of array returns The IP address of the server under which the current script is executing. SERVER_NAME − Name of server hostunder which the current script is executing.In case of a ever running locally, localhost is returned QUERY_STRING − A query string is the string of key=value pairs separated by & symbol and appended to URL after ? symbol. For example, http://localhost/testscript?name=xyz&age=20 URL returns trailing query string REQUEST_METHOD − HTTP request method used for accessing a URL, such as POST, GET, POST, PUT or DELETE. In above query string example, a URL attached to query string wirh ? symbol requests the page with GET method DOCUMENT_ROOT − returns name of directory on server that is configured as document root. On XAMPP apache server it returns htdocs as name of document root

C:/xampp/htdocs DOCUMENT_ROOT − This is a string denoting the user agent (browser) being which is accessing the page.

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36 REMOTE_ADDR − IP address of machine from which the user is viewing the current page. SERVER_PORT − port number on which the web server is listening to incoming request. Default is 80

PHP Complete Form Example

PHP - Keep The Values in The Form

To show the values in the input fields after the user hits the submit button, we add a little PHP script inside the value attribute of the following input fields: name, email, and website. In the comment textarea field, we put the script between the and tags. The little script outputs the value of the $name, $email, $website, and $comment variables.

Then, we also need to show which radio button that was checked. For this, we must manipulate the checked attribute (not the value attribute for radio buttons):

AJAX is a new technique for creating better, faster, and more interactive web applications with the help of XML, HTML, CSS and <a href="/tags/Java_(software_platform)/" rel="tag">Java</a> Script. Conventional <a href="/tags/Web_application/" rel="tag">web application</a> transmit information to and from the sever using synchronous requests. This means you fill out a form, hit submit, and get directed to a new page with new information from the server. With AJAX when submit is pressed, JavaScript will make a request to the server, interpret the results and update the current screen. In the purest sense, the user would never know that anything was even transmitted to the server. For complete learning on AJAX, please refer to AJAX Tutorial. </p><p>PHP and AJAX Example </p><p>To clearly illustrate how easy it is to access information from a database using Ajax and PHP, we are going to build MySQL queries on the fly and display the results on "ajax.html".

AJAX is a technique for creating fast and dynamic web pages. </p><p>Ajax refers to JavaScript and XML, technologies that are widely used for creating dynamic and asynchronous web content. While Ajax is not limited to JavaScript and XML technologies, more often than not they are used together by web applications. The focus of this tutorial is on using JavaScript based Ajax functionality in JavaServer Faces web applications. AJAX is a technique for creating fast and dynamic web pages. AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page. </p><p>Classic web pages, (which do not use AJAX) must reload the entire page if the content should change. </p><p>Ajax and forms: </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p> jQuery's ajax capabilities can be especially useful when dealing with forms. There are several advantages, which can range from serialization, to simple client-side validation </p><p>1) Serialization: Serializing form inputs in jQuery is extremely easy. Two methods come supported natively: .serialize() and .serializeArray(). While the names are fairly self-explanatory, there are many advantages to using them. </p><p>The .serialize() method serializes a form's data into a query string. For the element's value to be serialized, it must have a name attribute. Please note that values from inputs with a type of checkbox or radio are included only if they are checked. // Turning form data into a query string. $( "#myForm" ).serialize(); Creates a query string like this: field_1=something&field2=somethingElse </p><p>While plain old serialization is great, sometimes your application would work better if you sent over an array of objects, instead of just the query string. For that, jQuery has the .serializeArray() method. It's very similar to the .serialize() method listed above, except it produces an array of objects, instead of a string. </p><p>/ Creating an array of objects containing form data </p><p>$( "#myForm" ).serializeArray(); Creates a structure like this: </p><p>[ { name : "field_1", value : "something" </p><p>PROF.

Coarse-grained 3. Loosely coupled 4. Capability to be synchronous and asynchronous 5. Supports RPC </p><p>2. XML-based </p><p>Web services use XML at data representation and data transportation layers. Using XML eliminates any networking, <a href="/tags/Operating_system/" rel="tag">operating system</a>, or platform binding. Web services-based applications are highly interoperable at their core level. </p><p>3. Cross-gained </p><p>In the coarse-grained operation, a few objects hold a lot of related data. It provides broader functionality in comparison to fine-grained service. It wraps one or more fine-grained services together into a coarse-grained service. It is fine to have more coarse-grained service operations. </p><p>4. Loosely Coupled </p><p>A tightly coupled system implies that the client and server logic are closely tied to one another, implying that if one interface changes, the other must be updated. Adopting a loosely coupled architecture tends to make software systems more manageable and allows simpler integration between different systems. </p><p>5.

Synchronous Web services are served by RPC- oriented messaging. </p><p>Asynchronous Web services are invoked over existing Web protocols by a client who does not wait for a response. The document-oriented messaging often used for asynchronous Web services. Asynchronous Web Service is a crucial factor in enabling loosely coupled system. </p><p>Servlets, HTTP, and XML/SOAP are used to implement synchronous or asynchronous endpoints. </p><p>6. Supports RPC </p><p>A web service supports RPC through offering services of its personal, equivalent to those of a traditional aspect. </p><p>. A web service is a web resource. We can access a web service using platform-independent and language-neutral web protocols, such as HTTP. HTTP ensures easy integration of heterogeneous environment. . A web service is typically registered. It can be located through a web service registry. A registry enables service consumers to find service that matches their needs. The service consumers may be human or other application. . A web service provides an interface (a web API) that can be called from another program. The application-to-application programming can be invoked from any application. </p><p>Architecture of Web Services The Web Services architecture describes how to instantiate the elements and implement the operations in an interoperable manner. </p><p>PROF.

The interaction involves the three operations: publish, find, and bind. These operations and roles act upon the web services artifacts. The web service artifacts are the web service software module and its description. </p><p>The service provider hosts a network-associable module (web service). It defines a service description for the web service and publishes it to a service requestor or service registry. These service requestor uses a find operation to retrieve the service description locally or from the service registry. It uses the service description to bind with the service provider and invoke with the web service implementation. </p><p>The following figure illustrates the operations, roles, and their interaction. </p><p>PROF.

L-RPC parameters are a simple list of types and content - structs and arrays are the most complex types available. XML-RPC has no notion of objects and no mechanism for including information that uses other XML vocabulary.

PHP frameworks provide code libraries for commonly used functions, cutting down on the amount of original code you need to write. </p><p>Why Use a PHP Framework? </p><p>There are many good reasons for using PHP frameworks as opposed to coding from scratch. </p><p>1. Faster Development </p><p>Because PHP frameworks have built-in libraries and tools, the time required for development is less. </p><p>For example, the CakePHP framework has the Bake command-line tool which can quickly create any skeleton code that you need in your application. </p><p>Several popular PHP frameworks have the PHPUnit library integrated for easy testing. </p><p>2. Less Code to Write </p><p>Using functions that are built-in to the framework means that you don’t need to write so much original code. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>3. Libraries for Common Tasks </p><p>Many tasks that developers will need to do within web apps are common ones. Examples are form validation, data sanitization, and CRUD operations (Create, Read, Update, and Delete). Rather than having to write your own functions for these tasks, you can simply use the ones that are part of the framework. </p><p>4. Follow Good Coding Practices </p><p>PHP frameworks usually follow coding best practices. For example, they divide code neatly into a number of directories according to function. </p><p>They force you to organize code in a cleaner, neater, and more maintainable way. </p><p>Frameworks also have their own naming conventions for entities which you should follow. </p><p>5. More Secure Than Writing Your Own Apps </p><p>There are many PHP security threats including cross-site scripting, SQL injection attacks, and cross-site request forgery. Unless you take the right steps to secure your code, your PHP web apps will be vulnerable. </p><p>Using a PHP framework is not a substitute for writing secure code, but it minimizes the chance of hacker exploits. Good frameworks have data sanitization built-in and defenses against the common threats mentioned above. </p><p>6. Better Teamwork </p><p>Projects with multiple developers can go wrong if there isn’t clarity on: </p><p> Documentation  Design decisions  Code standards </p><p>Using a framework sets clear ground rules for your project. Even if another developer isn’t familiar with the framework, they should be able to quickly learn the ropes and work collaboratively. </p><p>PROF.

Easier to Maintain </p><p>PHP Frameworks encourage refactoring of code and promote DRY development (Don’t </p><p>Repeat Yourself). The resulting leaner codebase needs less maintenance. </p><p>You also don’t have to worry about maintaining the core framework, as that’s done for you by the developers. </p><p>PHP is far from dead.  In fact, it's used by about 79% of all websites!  Learn more about PHP frameworks in this guide 혏CLICK TO TWEET </p><p>What You Need to Know Before Using a PHP Framework </p><p>The first thing you need to know before using a PHP framework is PHP itself! If you don’t have a good command of the language, you will struggle to pick up a framework. Most frameworks run with PHP version 7.2 or later. </p><p>If you need to brush up on your PHP, read these articles: </p><p> Best PHP tutorials  PHP 7.4 (the current version)  PHP 8 (the next version) </p><p>Next, you should have built some PHP applications of your own, so you have a clear understanding of what’s required on the frontend and backend. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Knowing object-oriented PHP is also a must, as most modern PHP frameworks are object- oriented. Make sure you understand concepts like classes, objects, inheritance, methods, traits, and access modifiers. </p><p>Since many web apps connect to a database, you should know about <a href="/tags/Database/" rel="tag">databases</a> and SQL syntax. Each PHP framework has its own list of supported databases. </p><p>Understanding an Object-Relational Mapping (ORM) model is useful. ORM is a method of accessing database data using object-oriented syntax instead of using SQL. This means you can write your database queries in familiar PHP, although there may be times where you want to use SQL. </p><p>Many PHP frameworks have their own ORM built-in. For example, <a href="/tags/Laravel/" rel="tag">Laravel</a> uses the Eloquent ORM. Others use an open source ORM like Doctrine. </p><p>Understanding how web servers like Apache and Nginx work is helpful. You may need to configure files on the server for your app to work optimally. </p><p>You will probably do much of your development locally, so you need to know about localhost, too. Another option is to create and test your app in a virtual environment using Vagrant and VirtualBox. </p><p>Model View Controller architecture </p><p>PHP frameworks typically follow the Model View Controller (MVC) design pattern. This concept separates the manipulation of data from its presentation. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Model View Controller Process (Image source: Wikimedia Commons) </p><p>The Model stores the business logic and application data. It passes data to the View, the presentation layer. The User interacts with the View and can input instructions via the Controller. The Controller gives these commands to the Model, and the cycle continues. </p><p>In a nutshell, the Model is about data, the View is about appearance and the Controller is about behavior. </p><p>An analogy of the MVC pattern is ordering a cocktail at a bar. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>The User is the patron who arrives at the bar (the View) in need of refreshment. The User gives their drink order to the bartender (the Controller). </p><p>The Controller makes up the order from the Model – the recipe, ingredients, and equipment. Depending on the cocktail, they might use any of the following items, or others: </p><p> Alcohol  Fruit juice  Ice  Lemon  Glass  Cocktail shaker  Olive  Stirrer </p><p>The finished cocktail is placed on the bar for the User to enjoy. Should the User want another drink, they must speak to the Controller first. They are not permitted to access the Model and mix their own drink. </p><p>In PHP application terms, the MVC could correspond to the following: </p><p> Model: a database  View: a HTML page or pages  Controller: functions to access and update the database </p><p>Being comfortable using a command-line interface (CLI) helps when using a PHP framework. </p><p>Laravel has its own CLI, Artisan Console. Using the make command in Artisan you can quickly build models, controllers, and other components for your project. </p><p>Familiarity with the command line is also key to using the <a href="/tags/Composer_(software)/" rel="tag">Composer</a> PHP package manager. The <a href="/tags/Yii/" rel="tag">Yii</a> Framework is one of several which uses Composer to install and manage dependencies, packages which are required for an application to run. </p><p>Packagist is the main repository of packages that you can install with Composer.

You don’t want to invest precious time learning a framework if it’s too tricky to grasp. Luckily, PHP is one of the best programming languages to learn. </p><p>Next, you want a framework that is easy to use and saves you time. </p><p>A PHP framework should meet your technical requirements for a project. Most frameworks will have a minimum PHP version and certain PHP extensions that they work with. Make sure that your framework supports your database(s) of choice, and that you can use the framework with the web server that you want to deploy to. </p><p>Choose a framework with the right balance of features. A feature-rich framework can be a boon for some projects. On the other hand, if you don’t need many features, pick a framework that is stripped down and minimal. </p><p>Some desirable features are: </p><p> Testing  Cache storage  Templating engine: a way to output PHP within HTML using a PHP class  Security </p><p>If you need to build an application that is scalable, select a framework that supports this. </p><p>Finally, good documentation and support are important so that you can make the most of your PHP framework. A framework with a large and vibrant community is also more likely to stand the test of time and is also able to assist you when you run into difficulties. </p><p>Suggested reading: How to Improve PHP Memory Limit in WordPress. </p><p>PROF.

The Joomla community itself includes a vetted directory of such providers at the Joomla Resource Directory. </p><p>Easy Updates </p><p>There is always a challenge for the developers to keep the software up to date. Joomla consists of an in-built updater to make the updation process easy for the users, and it does not require any professional skills. It contains the "One Click Version Update" feature, which is super easy to use. </p><p>The built-in updater also comes with the automated checker, which provides notification if any update is there for your software. This feature also includes core software and Joomla extension that utilize this feature. It is always the best thing to keep the software up to date so that you can secure your web assets. Joomla also sends an email notification if there is an availability of a new Joomla version. </p><p>Integrated Help System </p><p>Joomla also provides an in-app contextual help option that is useful for every level of user to learn how to operate Joomla. Most of the pages include the help button on the top right side, which helps the users to understand all the options available on that page. There is a version checker that makes sure you are using the latest version and a system information tool, which helps you troubleshoot the issues. If you still have any issue, then link to a wealth of online resources for additional help and support are available, such as Joomla Documentation and User Forum. </p><p>Banner Management </p><p>There is also an option to easily add advertising and monetize the website with the help of banner management.

It is very easy to create the content using WYSIWYG (What You See Is What You Get) editor. It is easy to use and allows users to edit the content without any knowledge of code. After the content is created, you can use different pre-installed modules to show popular articles, latest articles or related topics, etc. You are not required to learn any syntax or remember the module details to manage the contents as the user interface performs it for you. </p><p>Administrators have the authority to add custom fields to the articles, as well as the users, contacts, and extensions. </p><p>Frontend Editing </p><p>Editing the content is very easy and fast. Assume that you are reading through your website, and you see any mistake or any other change that you want to make. You don't need to login </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p> to the administrative section for simple edits of contents and modules. You can simply perform it from the frontend by using the 'edit' option. </p><p>Powerful Extensibility </p><p>Joomla has a powerful extensibility feature. You can get over 7500 extensions to extend your website and broaden its functionality. You can use Joomla extension finder or Joomla Extensions Directory to get several ways to enhance Joomla as per your needs. </p><p>Architecture of Joomla </p><p>Joomla is written in PHP and based on MVC (Model-View-Controller) design pattern. It uses MySQL (MS SQL version 2.5 or above, and PostgreSQL version 3.0 or above) to store data. There are various features (e.g., page caching, blogs, polls, language internationalization support, and RSS feeds, etc.), which make Joomla an excellent choice for CMS (Content Management System). </p><p>In this article, we have demonstrated the architectural design of Joomla. </p><p>The below diagram shows the structural architecture of Joomla: </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>The architecture of Joomla includes the following layers: o Database o Joomla Framework o Components o Modules o Plugin o Templates o Web Server </p><p>Database </p><p>The Database consists of data except image files and documents which can be stored, manipulated, and organized in a specific manner. It includes the user information, content, and other required data of the site. It also contains the administrative information so that an admin can securely access the site and manage it. Joomla database layer is one of the most important factors which ensure the maximum flexibility and compatibility for the extension. </p><p>Joomla Framework </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>The Joomla Framework contains the collection of open-source software libraries/packages, on which Joomla content management system is built on. There is no need to install the Joomla Framework to use the CMS or vice-versa. Joomla Framework provides a group of files which is useful to create both web and command-line applications. It breaks the framework into single modular packages, and further, it helps each package to develop more easily. </p><p>Components </p><p>Components are referred to as mini-applications which contain two parts: o Administrator o Site </p><p>Whenever a page is loaded, the component is called to render the body of the main page. The Administrator part manages the different aspects of the component, and the site part helps in rendering the page when any site visitor makes a request. Components are known as the important functional units of Joomla. </p><p>Modules </p><p>Modules can be defined as the lightweight extensions used to render pages in Joomla. They are used to display new data from the component. They can stand on its own and are managed by the 'Module Manager', which is itself a component. They look like boxes, such as the login module. They also help to display the new content and images when the module is linked to Joomla components. </p><p>Plugin </p><p>The Plugin can be explained as a very flexible and powerful Joomla extension, used to extend the framework. Plugins are few codes that execute on occasion of specific event triggers. It is generally used to format the output of a component or module when a page is developed. The plugin functions which are associated with an event are commonly executed in a sequence whenever a particular event occurs. </p><p>Templates </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Templates are used to manage the look of the Joomla websites. There are basically two types of templates available; Front-end and Back-end. The Front-end template is a way to manage the look of the website, which is seen by the users. The Back-end template is used to manage or control the functions by the administrator. Templates are the easiest way to build or customize the site. They are used to add maximum flexibility to make your site look attractive. </p><p>Web Server </p><p>It is a server used to connect users to the site. It provides web pages to the client. The HTTP (HyperText Transfer Protocol) is used to communicate between the client and the server. Lastly, a website is that where you and your users interact with. </p><p>How joomala work :- </p><p>Joomla! is the second most popular Content Management System (CMS) on the planet, only surpassed by WordPress. It’s currently used by over 3 percent of all sites on the internet and has amassed an impressive community of creators and developers. However, what does this mean for you? </p><p>By using Joomla!, you can create phenomenal websites with little-to-no programming knowledge. It’s a slightly more advanced solution than some of its competitors, but it still retains a user-friendly interface. What’s more, it’s a free and open-source platform. </p><p>In this article, we’ll dig deep into Joomla! and its history. We’ll discuss the platform’s pros and cons and talk about when you should consider it as the foundation for your website. Finally, we’ll show you how you can use Joomla! to create a new site. Let’s get started! </p><p>How Joomla! Works </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>As we’ve mentioned, Joomla! is a CMS. For the uninitiated, this is a type of application that can be used by multiple people to create, store, manage, and publish digital content. The most common use for any CMS is to create websites. </p><p>In contrast to WordPress, which was initially developed as a blog-centric platform, Joomla! was created from the start as a versatile CMS that could be used for almost any type of website. When it comes to the actual creation and maintenance of your site, Joomla! is in many ways similar to WordPress and other popular CMS options. It enables you to publish articles, expand your site’s functionality with extensions, and change its appearance via templates. </p><p>To use Joomla!, you can simply download it for free and install it on your website. However, you can also use the free Joomla! Launch service to create a website using the platform, without the need to have your own hosting. </p><p>We’re going to discuss the ins-and-outs of getting started with Joomla! in more detail later. First, however, let’s discuss why you might want to choose Joomla! in the first place. </p><p>When and Why You Should Use Joomla! to Create Your Website </p><p>Which platform and tools you use to create your website will ultimately depend on what type of site you intend to build, as well as your personal skills and preferences. As such, let’s look at the main advantages of Joomla!, to help you decide if it’s the right platform for you. </p><p>The first and arguably greatest advantage is Joomla!’s scalability and flexibility. Joomla! is also somewhat more technically complex than WordPress, offering more advanced configuration options. This means that Joomla! lends itself better to creating ambitious projects. After all, there’s a reason many university and business sites choose Joomla!. </p><p>Very experienced users can also take advantage of the Joomla! Framework, which lets you use the platform in even more intricate ways. For example, by using this framework you can create complex business directories, reservation systems, data reporting tools, and inventory control systems. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Despite its advanced features, Joomla! remains a user-friendly platform, which is still easy to use even if you have little-to-no experience in coding or website design. However, for a complete beginner, it will have a somewhat steeper learning curve than WordPress. Fortunately, the very active Joomla! community is always on hand to help out with documentation and direct support. </p><p>If you’re curious about Joomla! or still not sure whether it’s the right option for you, we recommend that you use the Joomla! Launch service mentioned above to create a free website. This will give you a chance to test out the platform, without making a firm commitment. </p><p>How to Get Started With Joomla! (In 4 Steps) </p><p>By now, you should have a solid idea about whether or not Joomla! is the best option for you and your website. Now, let’s look at the practical aspects of the platform. </p><p>In the following guide, we’ll show you how to set up your site, begin creating content, and expand it with extensions and templates. Let’s get started! </p><p>Step 1: Install Joomla! </p><p>Before you can do anything else, you’ll need to install Joomla! on your website. There are a few different ways you can go about this. </p><p>As we’ve mentioned, you can use Joomla! Launch to create a free site in minutes. However, this comes with a number of limitations. For instance, you’ll have to manually renew the site every 30 days to keep it online. As such, we don’t recommend that you use this service for a permanent website. </p><p>Instead, you can host your own website using one of two methods. The more advanced option is to perform a manual installation. This involves downloading Joomla! for free and installing it on your web host’s server. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>The general steps for doing this include: </p><p>1. Creating an SQL database for your site. 2. Uploading the Joomla! files to your site’s root directory. 3. Running the Joomla! configuration wizard, which you can reach by accessing your site’s URL. 4. Configuring your database. 5. Installing the included sample data and configuring your email. </p><p>This process is ideal for developers who want to be involved in each stage of the installation process. However, it can be a little too convoluted if you just want to get a website online. Fortunately, there’s a much easier way to do that – namely, using a one-click install option. </p><p>Some web hosts offer one-click installs for the most popular CMS platforms. For example, here at DreamHost we let you install many popular applications this way, and Joomla! is no exception. Therefore, let’s look at how to use the DreamHost one-click install option to get started with Joomla! quickly. </p><p>First, you will need to log in to your DreamHost control panel. </p><p>Then, navigate to Domains > One-Click Installs in the left-hand menu. This opens a page where you can see all the available one-click options. </p><p>Then, navigate to Domains > One-Click Installs in the left-hand menu. This opens a page where you can see all the available one-click options. </p><p>PROF.

YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Here, you can choose which of your existing domains you’d like to use, specify a subdirectory, and select a database to use. You can either pick an existing database or create a new one for this site. </p><p>When you’ve made your choices, click on Install it for me now! to create your new website. The application will be installed within a few minutes, after which you’ll receive an email with information about how to log in to your new site. You can then complete the configuration wizard that we mentioned earlier. </p><p>Step 2: Start Creating Content </p><p>Once you’ve completed the installation process, you’ll be able to access your Joomla! website. First, you’ll be asked to log in with your admin credentials. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>You’ll then be taken to your new site’s control panel. </p><p>As you can tell, there are a lot of options in this control panel. We’re just covering the basics in this guide. If you’d like to know more about what you can do in this interface, we recommend that you refer to the official documentation. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>For now, let’s focus on the most crucial tasks, starting with creating new content. If you’re familiar with WordPress or any other CMS, this process should offer few surprises. For the purposes of this example, let’s create a new post, which in Joomla! is called an ‘article.’ </p><p>To get started, click on New Article in the Content menu on the left-hand side of the screen </p><p>To get started, click on New Article in the Content menu on the left-hand side of the screen. </p><p>This will take you to Joomla!’s TinyMCE-based HTML editor, which you can use to write articles. </p><p>You can write your content in the main window, using the options menu right above it to format the text or add new elements. Above that, you’ll see a row of links. These will take you to additional options for the article. For example, you can use the Images and Links tab to set a main image for the article, as well as to add in links. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>We recommend that you explore the different tabs here and refer to the Joomla! documentation for assistance if needed. There are a lot of options but most are very self- explanatory. After just a few articles, you’ll likely find the editor quite intuitive to use. </p><p>When you’ve finished creating your first article, you can save and publish it. To do that, return to the Content tab and take a look at the options on the right. </p><p>Here you can assign the article to a category and give it tags, decide if it should be a featured item, and determine its visibility. When you’ve done that, click on one of the Save buttons, which are located in the top-left corner. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Once the article has been saved, you can check it out on your site. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>This is looking pretty good already. Of course, there’s a lot more you can accomplish when you’re more comfortable with the editor. For now, however, let’s turn our attention towards adding new features to your site. </p><p>Step 3: Add Extensions to Expand Your Site’s Functionality </p><p>Joomla! extensions work in much the same way as WordPress’ plugins do. In essence, they are collections of code that you can install on your site, which implement additional features. This option lets even a beginner or a non-coder create sites with advanced functionality. </p><p>There are thousands of extensions available for Joomla!, both free and premium. You can find many of them in the official Extensions Directory. </p><p>There are thousands of extensions available for Joomla!, both free and premium.

To do that, you’ll need to return to your site’s control panel, and access the Install Extensions option in the main menu. </p><p>This takes you to your Extensions page, where you can add and manage extensions. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Installing a new extension is as simple as dragging-and-dropping its ZIP file onto this page. Alternatively, you can select the Or browse for file button to find it on your computer. Either way, the extension will be uploaded and installed on your site. </p><p>Once the process has been completed, you’ll see a success message along with some information about the new addition. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>At this point, your extension is ready to go! You can now configure it or simply start using it, depending on the extension in question. </p><p>Step 4: Change Your Site’s Appearance With a Template </p><p>We all know it’s what’s on the inside that counts. However, that’s not to say your site’s look isn’t important too. You probably won’t want to stick with your new site’s generic standard design, after all. So let’s look at how to change things up using Joomla! templates. </p><p>These function just like WordPress themes, in that they change the appearance and layout of your site. As with extensions, there are plenty of free and paid options you can add to your site. You can find a lot of choices on sites like ThemeForest and RocketThemes. </p><p>To switch your site’s current template, you’ll need to find and download a new one from an external site. If you’re feeling up to the challenge, you can even create one yourself. When you have the ZIP file in hand, you’ll once again want to access the Extensions screen, just like you did in the previous section. </p><p>You can install a new template exactly like an extension. As such, drag your template’s ZIP file onto this screen or search for it on your computer. Once it’s installed, you’ll see a message letting you know that it’s been added successfully. </p><p>To actually use the new template, you’ll need to assign it to your site. It’s worth noting that Joomla! lets you do quite a lot of advanced things with templates. For instance, you can use more than one template on a site, which is something you can’t do in WordPress. </p><p>However, for now, let’s stick to the basics. You’ll want to add your new template and assign it, so start by clicking on Templates in your control panel menu. </p><p>This will open the Template Manager, where you can see all currently-installed templates. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>To set a template as your default, you only need to select the button marked with a star next to its name. </p><p>Once you’ve done that, you can view your site and see the new template in action. With that, you’ve successfully learned the basics needed to manage your Joomla! Website. </p><p>Extension Connection </p><p>When it comes to CMS platforms, Joomla! manages to be both user-friendly even to beginners, and still offer a powerful website management system. This is a platform that’s relatively easy to get started with, and it offers plenty of options to expand and scale your site. There’s also a stellar community that can assist you along the way. </p><p>Do you have any questions about using Joomla! to create a website?

If you don’t even know where to start on this topic, read our post on how to choose a domain name and our comparison of web hosting services. </p><p>We recommend choosing something cheap to get started with your project. Yet, whichever web host you pick, make sure it meets Joomla’s system requirements. </p><p>2. Install and Set Up Joomla </p><p>The first step of the tutorial: how to install and set up Joomla. There are two ways: </p><p>2a. Using Bluehost and Quick Install </p><p>Once you’ve signed up and grabbed a domain at Bluehost, log into your account and click on Advanced in the left column. </p><p>PROF.

Unless you have a good reason to change it, just leave everything as is.  Site Settings — This is the site name and description that will appear in search engines. Therefore, it’s a good idea to change the default. However, you can also do it later inside Joomla itself so don’t stress out about it too much.  Database Settings — This is an option to include sample data on your site. Since, in this tutorial, we want to learn Joomla from scratch, we will leave it at None.  Admin Account — Make sure to choose a secure username and password for your administration account and enter your real name and email address.  Choose Language — If you want your Joomla installation in any other language than English, you can change it here.  Advanced Options — In this place, you can modify your database name, table prefix, disable email notifications for available updates, and control whether Joomla should automatically update or not. These settings are all optional and you can usually leave them as they are. Once you are done, click Install at the bottom. When you do, you might run into the warning below. </p><p>PROF.

Manual Installation (Any Web Hosting) </p><p>If you are with a hosting provider that does not have the option above, you will have to install Joomla manually. Don’t worry, it’s very easy. </p><p>1. Create a Database and Upload Files </p><p>The first step is to create a MySQL database. This is where Joomla stores all of your content and it is a vital part of any website built with the CMS. You should find options to create one in your host’s control panel. </p><p>PROF.

For that, head on over to the download section of the Joomla homepage and hit the big green download button (at the time of this writing, Joomla 3 is the latest major version, with Joomla 4 in beta status). </p><p>Make sure to save the zip file to your hard drive and, when it’s finished, extract all files. After that, connect to your server via FTP (e.g. through FileZilla) and upload the extracted files to where your domain is pointing (usually the root directory). Once that is finished, it’s time to move on to the next step. </p><p>2. Run the Manual Installation </p><p>When all files are on your server, open a browser window and input your site URL. If you have done everything right, this should start the Joomla installation process. </p><p>PROF.

Below that, enter your site’s name and, optionally, a description. As mentioned, this is the stuff that will show up in search engines but you can also change it all later if you are not happy with your first choices. </p><p>On the right, you will be asked to enter the information for your Super User account. That is the main administrator, so be sure to enter a valid email address, a user name that isn’t easy to guess, and a safe password (twice). </p><p>Finally, at the bottom, you can select to set your site’s front end to offline mode after installation.

Fill everything in like so: </p><p> Database Type — In most cases, you can simply leave this as is.  Host Name — This is the hosting location of your database. Change it if it’s anything else than localhost.  Username — The username associated with your database.  Password — In this field goes the password for your MySQL database.  Database Name — Here, include the name of the database you want to connect your Joomla website.  Table Prefix — Unless you have good reason to change this, use the randomly generated prefix offered by the installation.  Old Database Process — If there is already any data in your database, you can choose whether Joomla should delete or save it. Again, once you are ready, hit the Next button. </p><p>PROF.

When all of that is the case, you can click Install. Joomla will then set up the CMS on your server. Once finished, you will see this screen: </p><p>PROF.

This will get rid of sensitive files on your server. </p><p>That’s it! Cool beans, you just installed Joomla completely by hand. </p><p>3. Get Familiar with Joomla Basics </p><p>At this point, when you go to the address where your new Joomla website lies, the front end looks like this: </p><p>PROF.

On the right is important information about the state of your site. </p><p>The Heart of Joomla: The Taskbar </p><p>However, the most important part is the taskbar at the top. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Here, you find the same options as in the control panel and then some. This is what the different menus contain: </p><p> System — Access to the control panel, site settings, pending or locked content items, the option to clear cache, and view system information (site, server, and environment).  Users — Manage users, user groups, and access levels, add notes about users, deal with privacy related requests, view user logs, and mass email everyone on your site.  Menus — As the name suggests, this contains all options about the creation and management of menus.  Content — Add articles and taxonomies, assign featured content, and manage your site’s media files.  Components — Create and manage site banners, contacts, site updates, private messages, multilingual associations, and news feeds. It also provides access to post- installation messages (we already covered those), lets you set up redirects (though you need a plugin for that), view site search terms, use the smart search (again, this needs a plugin), and manage tags.  Extensions — Allows you to install, update, manage, configure, find, and troubleshoot extensions. In this menu, you can also see the state of your database and update your site.  Help — Direct access to important help topics in the official documentation. All clear so far? Then let’s move on. </p><p>4. Select a Template for Your Site </p><p>Like other CMS, Joomla offers a way to change your site design without coding, which is what we will look at in this step of the tutorial. In Joomla, your entire website’s look, feel, and functionality are entirely dependent on so-called templates. </p><p>There are free and premium (paid) Joomla templates available. However, finding one can be tricky. Unfortunately, the CMS does not have a central directory for this. Therefore, you need to look to shops to find them. Many of those who sell premium themes also offer free versions you can test drive. Here are a few places to get started: </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p> TemplateMonster  Joomlart  Joomdev  JoomShaper </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>When selecting a template, besides your own taste, pay attention to a few important characteristics: </p><p> Support — It’s great to have technical support included, to have someone to help you with issues.  Updates — Joomla constantly updates their system. Make sure your template provider does the same with their products so they will work with the latest release.  Documentation — From time to time, you’ll need to check some features to learn how they work. Be sure there is a place where you can do so.  Customizability — Check out which template features can be customized by yourself. For example, look for templates that have many module positions (more on that soon). </p><p>5. Install Your Joomla Template </p><p>Installing a template in Joomla is quite easy in principle. Once you have made a choice, you usually get it in the form of a zip file. This you can simply upload under Extensions > Manage > Install. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Either drag and drop the file into the field or click the Or browse for file button to find it on your hard drive. Select it and Joomla should do the rest by itself. Alternatively, you can also install the template via its URL if you know where the package is located. </p><p>After that, you still need to activate the template under Extensions > Template > Styles. Here, click the star icon to the right of the template name to make it the default for the entire site. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>When you now go back to the front end of your site, you will see that its entire design has changed. Such is the power of templates. </p><p>Note that, when downloading your template, you might get additional files such as quickstart, settings, and extension. </p><p>The first is a complete version of Joomla including the template. When you install that, your new design is ready to go when your site is set up, often including demo content. It’s a shortcut when you want the exact design as the template advertises. All that’s left to do is exchange the content. </p><p>The other two files refer to stuff that you might have seen in the template demo site, such as sliders, etc. </p><p>6. Customize the Design </p><p>Most templates come with at least some customization options. You can access them by clicking on the template name in the list. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>In the settings, you can make adjustments to things like colors, fonts, logos, sizes, and much more. In this case, the template even comes with its own settings page that we get to when we hit Template Options. </p><p>Some Joomla templates also have a preview option where you can see changes in real-time. In either case, don’t forget to check out what your template has to offer and to save any changes you have made to translate them to your site. For example, below we have changed the social profiles and contact information in the top bar disabled the branding at the bottom and moved the top bar to the bottom of the page via the Layout options. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>7. Create Content Using Joomla Modules </p><p>Right now, even if it looks better, your site is still pretty empty. Time to change that. At this point in our tutorial, we will go over how to use Joomla to create content. </p><p>Unfortunately, we have to start with one of the more complicated topics, which is modules. These are little units of content that can appear in many places on a page like building blocks. Using them takes some getting used to, so let’s try it out on the homepage. </p><p>To understand your options, it’s best to start by enabling the preview mode for module positions. For that, go to System > Global Configuration > Templates. Here, set Preview Module Positions to Enabled, save, and close. </p><p>Then, go back to your list of templates and click the Preview button (the eye icon). This will then display all available positions on your page where you can add modules and the names of the positions. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Quick note: Don’t forget to switch the preview off when you are done assigning modules. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>8. Assign Modules to Positions </p><p>Alright, now that you know where your modules can go, how do you assign them to those positions? All of that happens under Extensions > Modules. </p><p>Here, you can see all modules currently active on your site plus the positions, pages, users, and languages they are assigned to. To get rid of anything already on your site, such as the login form and breadcrumbs, simply click the downward arrow button under Status and select Trash. </p><p>If you want to add more modules to your site, under New in the upper left corner, you find a whole lot of options. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Let’s say you wanted to include some text about you and your site on the homepage. The first thing to check is where on the page it should go. In this case, this is content-bottom. </p><p>Then, go to the Modules menu, create a new module via the green button in the upper left corner, and choose Custom as the type. This allows you to create your own content block using a WYSIWYG (what you see is what you get) editor. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>This is simply a tool for creating and formatting content that lets you view what you are doing. Unfortunately, if we went over all of the options on this screen, the Joomla tutorial would get way too long. However, if have ever used a word processor, everything should look very familiar. </p><p>In addition, you can hover over any of the icons to get a description of what it does. This way, you should be able to quickly figure out how to write and format text, insert headings, images, and other media, and anything else it has to offer. </p><p>When you are done, make sure that when you save, Status on the right is set to Published and that you pick the correct template location under Position (pay attention that you also select your active theme!). In this case, we also want to hide the module title. </p><p>PROF.

In this case, it’s Only on the pages selected and then Home. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Save and you should see it on your homepage (and only there). </p><p>PROF.

In addition, you can also add new modules via extensions (more on that below as well). </p><p>For example, this is what the homepage looks like when we add the main image in form of a slider at the hero-section position with the help of a plugin and move the text module to content-top: </p><p>PROF.

Create New Pages </p><p>Now for something easier: pages. The first thing to learn here is that you create them in one place and make them appear in another. This is a general thing to keep in mind throughout the tutorial that anything you make in Joomla won’t automatically show up on your site. </p><p>In this CMS, pages are simply called articles. This can be a little confusing you come from a blogging background but don’t let that hold you up. You can create articles via Content > Articles > Add New Article. Alternatively, use the shortcut on the control panel. Both will get you to a very similar editing screen as you used before. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Create and format content the same way as you did earlier. When you are done, under Alias you are able to determine a permalink (meaning page URL). It often makes sense to put a keyword here instead of using the article title. Under Status make sure that it is set to Publish before saving. </p><p>10. Assign Pages to the Joomla Navigation Menu </p><p>PROF.

For that, under Menus, find the one with the house icon assigned to it. That is your currently active one. </p><p>To assign a new link to it, hover over it and pick Add New Menu Item. Doing so will take you to the screen below. </p><p>PROF.

Add a Blog Section </p><p>Publishing blog posts in Joomla basically works the same way as creating pages. The only difference: you assign your blog posts to a category. For that, we first need one. </p><p>Go to Content > Categories > Add New Category. It takes you to the same editor as before. In this case, you only have to input a name at the top (e.g. Blog) then save and close. </p><p>After that, you can assign the category to your menu the same way you did with the page before. Only this time, under Menu Item Type, choose Articles > Category Blog. </p><p>Make sure to select your Blog category under Choose a Category. Then, check that it’s assigned to the right menu and give it a menu title that makes sense. Save and close to get it on your site. From now on, any article that you assign to your Blog category will show up in the form of a blog post under that menu item. </p><p>PROF.

With more than 6,000 available extensions, it can be difficult to make a choice, so you can start with collections like this: </p><p> Joomla Extensions: 101 Essential Extensions You Need In Your Life Now  17 Best Joomla Extensions And Components You Must See (2021)  25 Best Joomla Extensions in 2020 </p><p>PROF.

You can find all extensions under Extensions > Manage > Install. When you are there for the first time, at the top, use the option to set up Install from web. When you do, it gives you access to everything in the Joomla extension directory right from your back end. </p><p>Click on any extension and then hit the Install button (twice) to automatically load it onto your site. Should this not work for you for some reason, you can simply download the extension or copy the URL where it is located. After that, you are able to use the Upload Package File and Install from URL tabs to get it on your site. </p><p>PROF.

Unfortunately, it’s a bit confusing and crowded, so you might have to search for your extension by name. </p><p>For this example, we have installed the popular JCE content editor. With it present and active and after setting it as the default editor under System > Global Configuration, the content creation experience changes notably. </p><p>PROF.

The CMS is powerful, flexible, widely extendable, and also free of charge. </p><p>In this Joomla tutorial, you have learned how to install the platform, find your way around its back end, change your site design, add content, and install extensions. </p><p>Of course, there is a lot more to learn. However, you now know enough about how to use Joomla to start exploring on your own. If you want to dive deeper into the platform, here are some recommended resources: </p><p>PROF.

Powerful and lean, it’s perfect for enterprise business sites that need to maximize performance. However, diving into Drupal can seem daunting at first glance. </p><p>Fortunately, there are ways to demystify Drupal. There is something of a steep learning curve, but you don’t need to have a deep technical background in order to master it. With a beginner’s guide (and a little patience) anyone willing to take some extra time can how to use this CMS effectively. </p><p>In this post, we’ll tell you a bit about the history of Drupal, as well as the advantages of the platform over other website builders. This will help you decide if it’s worth investing the time and effort required to learn it. Finally, we’ll offer a short guide on how to get started. Let’s begin! </p><p>How to Get Started with Drupal </p><p>As we’ve mentioned, Drupal can seem daunting at the start. However, getting started and beginning to experiment with its powerful systems is well within reach. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>There are a few simple steps you can follow, if you want to create a new Drupal site as a complete newbie: </p><p> Purchase a hosting plan with one-click install feature. A hosting plan with Drupal pre- loaded saves you the trouble of figuring out how to install it yourself – which is perfect for beginners (plus, our Drupal hosting comes already optimized for speed and performance).  Familiarize yourself with the platform. You can either buy a book, or peruse one of the many free online tutorials for beginners.  Understand the terms. Skim through Drupal’s helpful glossary to familiarize yourself with key phrases you’ll need to know.  Get to know the core modules. The core modules are at the heart of Drupal. Understanding what they are and how they work is vital.  Begin building your site. As we’ve discussed, Drupal 8 comes with a WYSIWYG editor that you can use to start adding text and images to your pages right away.  Ask for help when needed. For anything you don’t understand, Drupal has an active forum that’s very accepting of questions.  Consider hiring a professional. If you’re lost, or if you’re creating a very complex site, consider hiring a professional to get the ball rolling. Then, focus on learning how to update </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p> content and make small changes once your site’s framework is in place. For example, if you can’t find a module that does what you want, you may end up needing to hire a <a href="/tags/Programmer/" rel="tag">programmer</a> to build you something custom. </p><p>Drupal is a flexible and powerful solution for websites. This is especially true if you either have some coding experience yourself, or the resources to hire a designer. Once you put in the effort to learn how the system works, you’ll be able to take advantage of its security and enterprise-level scaling ability (among other advantages). </p><p>Development started on Drupal 8 features back in March of 2011. Since then, the developer and application framework world has looked forward to the outcomes of every development, feature completion, clean-up, API completion, beta, and release candidate (RC) phase with baited breath. In November of 2015, Drupal 8.0.0 was released. Sighs of relief turned to curious murmers—what's this all about? </p><p>Drupal 8 takes an already terrific content management framework to ever greater heights for users, administrators, and developers. There's a seriously sharp focus on user-friendliness, but content presentation, new ways to create data structures, build <a href="/tags/API/" rel="tag">APIs</a>, multilingual capabilities, and the delivery of mobile accessibility out of the box? Drupal 8 brings those to the table too. </p><p>While Symfony 2 powers the Drupal 8 backend, a lighter and faster core offers tons more apabilities for modules and themes. Plus, the Drupal 8 migration and the onward curve is significantly reduced. These changes and more are key reasons to consider that switch to Drupal 8. </p><p>Drupal 8 Features Worth Knowing: 1. New Theme Engine Drupal 8 includes a brand new theming engine called <a href="/tags/Twig_(template_engine)/" rel="tag">Twig</a>, which is PHP-based, flexible, fast, and secure. It's much easier to create beautiful and more functional Drupal websites usingTwig, as its templates are written in a syntax that's less complex than a PHP template or others while being more secure. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>1. Mobile First From The Get-Go Drupal 8 is mobile first in its approach. All the built-in themes that come with Drupal 8 are responsive, along with an admin theme that adapts to different screen sizes, and a ‘Back To Site’ button to go back to the front page. Tables fit into any screen size without a hitch, and the new admin toolbar works well on mobile devices. </p><p>2. More HTML5 Power To You HTML5 is now more or less the de facto standard when it comes to writing web markup. The same is now available natively in Drupal 8, giving you access to input fields like date, e-mail, phone, etc., and even more functionality and compatibility with mobile and handheld devices. </p><p>1. Multilingual Ready Drupal 8 boasts extensive multilingual features right out of the box. The admin interface has built-in translations. You can also create pages with language-based Views filtering and block visibility. Translation updates from the community are automatically facilitated. </p><p>2. Manage Your Configuration Drupal 8 has configuration management built into it at the file-system level so that carrying over configuration elements (like content type, views, or fields, etc.) from local development to the server is a breeze. You can use a version-control system to keep track of configuration changes. Configuration data is stored in files, separate from the site database(s). </p><p>Easy Authoring New Drupal 8 features bring unprecedented power into the hands of the Content Editor, with WYSIWYG editor CKEditor now bundled with the core. However, the most touted improvement remains the in-place editing capability that Drupal 8 will afford users, a result of the Spark Initiative. </p><p>Site and content creators or editors can edit text on any page without having to switch to the full edit form. Drafts are now much easier to create, and web security is now better implemented as a result. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>1. Quick Edits There's something great about seeing something that needs changing and having the ease of access to change it—directly and quickly. Now Quick Edit is a backport of the Drupal 8 in- place editing for Fields. So if you're logged into Drupal content is in front of you, edit the text directly for quick fixes and additions from the front-end. </p><p>2. Views Now Part Of Core Views sit high up in the Drupal module hierarchy, as it is an integral part of most website projects, and a lot is pretty much impossible without it. Site designers have used use this hitherto-contributed module to output galleries, maps, graphs, lists, posts, tables, menus, blocks, reports, and what-have-you. With this Drupal 8 feature, Views is part of and firmly integrated with the core. </p><p>1. The front page and several administration pages are now Views, and users will now be able to quickly create pages, blocks, admin sections, etc., and modify existing ones just as effortlessly. </p><p>2. Better Support For Accessibility Drupal 8 has excellent support for industry standard accessibility technologies, like WAI- ARIA. ARIA Live Announcements API and TabManager are significant improvements in Drupal 8, which provide control for rich Internet applications. Bells and whistles like better font sizes, tweaked color contrasts, jQuery UI’s autocomplete, and modal dialogs go a long way towards making Drupal 8 a breeze to use. </p><p>1. Web Services Built-In Drupal 8 now makes it possible to use itself as a data source, and output content as JSON or XML. You can even post data back to Drupal 8 from the front end. Hypertext Application Language (HAL) is implemented in Drupal 8 and makes exploitation of web service capabilities less painful. </p><p>2. Fields Galore </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>1. Drupal 8 ships with bucket-loads of field types in the core, thus taking its content structure capabilities up a notch. New field types like entity reference, link, date, e-mail, telephone, etc., aid content creation, and now you can attach fields to more content types, as well as creaGuided Tour Now the descriptive text is right under the help link. Users can click and then take the tour; pop-ups appear, explaining how this all works, one of the most helpful Drupal 8 features to newcomers. This user-friendly boost is well-received as it's making the CMS easier for everyone to understand. </p><p>Guided Tour Now the descriptive text is right under the help link.

This user-friendly boost is well-received as it's making the CMS easier for everyone to understand. </p><p>1. Loading Speed Drupal 8 caches all entities and only loads JavaScript when necessary. When a page is viewed, its content doesn’t need to be reloaded again. Previously viewed content is quickly loaded from the cache. Once configured and enabled, caching is completely automatic. </p><p>2. Industry Standards Drupal 8 aligns with the latest PHP 7 standards like PSR-4, namespaces, and traits, and uses top notch, outstanding external libraries like Composer, PHPUnit, Guzzle, Zend Feed Component, Assetic to name a few. Meanwhile, underlying Drupal 8 features modern, object-oriented code that's the order of the day, by Symfony 2. </p><p>3. </p><p>1. JavaScript Automated Testing </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>Automated testing is not possible for front-end, so JaveScript (JS) automated testing is now possible with Drupal 8.1. Now QA'ers can test the JavaScript front-end automatically, saving time and making continuous integration that much easier. </p><p>2. Big Pipe In Core With Big Pipe part of Drupal core, developers can optimize the site load performance for the end-user significantly. While this feature has nothing to with actual performance and is only perceived, it's a great feature to have since the end user is able to see a difference in site load times. </p><p>The recommended way to install themes is with Composer. Drupal 8 places all core themes under a directory named /core/themes and all contrib or custom themes under a directory named /themes (in the webroot). Check the detail content of README.txt in the /themes directory for more info. 1. Download the theme. You can find themes on Download, as well as some external sites. Make sure the version of the theme matches your version of Drupal. When you first download the theme, it will appear in a compressed file format such as 'tar.gz' or 'zip'. You need to extract the compressed file then you will get a list of files extracted into a folder. </p><p>2. Upload the folder. FTP/Copy/SCP your files to the desired themes folder in your Drupal installation. Drupal 8 places all core themes under a directory named /core/themes and all contrib or custom themes under a directory named /themes (in the webroot). If you are running a multi-site installation multisite installation, you may also put themes in the sites/all/themes directory, and the versions in sites/all/themes will take precedence over versions of the same themes that are here. Alternatively, the sites/your_site_name/themes directory pattern may be used to restrict themes to a specific site instance. </p><p>3. Read the directions. If the theme has an installation file (usually INSTALL.txt and/or README.txt), read it for specific instructions. There are themes that require special treatment to function properly. </p><p>PROF.

Enable and make it the active, default theme. Go to "Appearance" (/admin/appearance) on the main Administration menu of your site. Check the 'Install' to install the theme and use "set as default' to enable the theme for your website. Alternatively, you can use 'Install and set as default' to enable the theme for your website along with theme installation. </p><p>5. Click the 'Save Configuration' button at the bottom. If you run into problems, check the themes issue queue and search the forums. If your problem hasn't already been addressed, post a question and someone will try to help you out. </p><p>How to Install Themes in Drupal 8 </p><p>Updated on Mar 13, 2019 </p><p>After you have installed Drupal 8, you can change the default theme (Bartik) to a new theme that suits your website's needs better. </p><p>To achieve this, you will need to login to your admin account and navigate to Manage → Appearance. </p><p>Here you can open the themes link in a new tab or navigate to the official Drupal website's Themes section by yourself. To directly upload a theme, click on the +Install new theme button. </p><p>PROF.

In order to upload a theme, you should go to the “sites/all/themes” folder of your template package and upload the “themeXXXX” folder to the “sites/all/themes” directory of your Drupal installation. 2. Open the "Appearance" menu. Locate the newly installed theme and click on Enable and set default. </p><p>PROF. YOGESH DESHMUKH www.dacc.edu.in </p><p>DNYANSAGAR ARTS AND COMMERCE COLLEGE, BALEWADI,PUNE – 45 </p><p>Subject: Advance PHP Subject code CA- 404 Class: SYBBA(CA) </p><p>3. You should upload modules and other files from the template package to be able to use all the features provided by the template. Go to the “sites/all” folder of your template and upload the “libraries” and “modules” folders to the “sites/all” folder of your Drupal installation. 4. Go back to the "sites" folder. Open the "default/" folder and upload its content to the "sites/default" directory on your server. DO NOT upload the "settings.php" and "default.settings.php" files. You may face some permissions issues here. Please check the screenshot below. Such issues are caused by the permissions which Drupal assigns for the “sites/default” folder. In our case the sites/default folder has 555 permissions. We are going to set 755 permissions. Do not forget to set the original permissions after you upload files. You can contact your hosting provider regarding the permissions issue. The hosting provider should be able to assist with these kinds of issues. </p><p>5. We can see that all the modules that come with the template are available. You may proceed to the template sample data installation. It will make the template look and work exactly like in the template live demo with sample content. </p><p>======end======</p><p>PROF.
