Preview Yii Tutorial (PDF Version) Yii About the Tutorial The Yii[ji:] framework is an open-source PHP framework for rapidly-developing, modern Web applications. It is built around the Model-View-Controller composite pattern. Yii provides secure and professional features to create robust projects rapidly. Audience The Yii framework has a component-based architecture and a full solid caching support. Therefore, it is suitable for building all kinds of Web applications: forums, portals, content managements systems, RESTful services, e-commerce websites, and so forth. Prerequisites Yii is a pure OOP (Object-Oriented Programming) framework. Hence, it requires a basic knowledge of OOP. The Yii framework also uses the latest features of PHP, like traits and namespaces. The major requirements for Yii2 are PHP 5.4+ and a web server.

  • The Yii Framework – Larry Ullman
    The Yii Framework – Larry Ullman This is a copy of the Larry Ullman series ‘Learning the Yii Framework’. See http://www.larryullman.com/2009/06/18/introduction-to-the-yii-framework/. 1. Introduction to the Yii Framework In 2009, I had three decent-size Web sites to develop, so I thought I might try using a PHP framework for the first time, instead of coding everything from scratch. I’ve used Ruby on Rails for Web development before, so I’m comfortable with frameworks and the MVC architecture, but I wanted to educate myself on PHP frameworks. After researching a handful of frameworks, and after an unsatisfying attempt to use Zend Framework, I finally settled on, and really came to appreciate the Yii Framework. At the time, the Yii Framework was still quite new, and there are still bugs to be worked out (for the more advanced stuff), but Yii works so well that it’s very easy to use. In this first of several posts on the Yii Framework, I just discuss setting up and testing Yii. (Note: In October 2010, I’ve updated this entire series to reflect changes in Yii since this series was written, and to take into account feedback provided through the comments. Some outdated material will be crossed out, but left in to reflect how things have changed since the series was begun in June 2009.) The first thing you need in order to use the Yii Framework is access to a Web server with PHP installed, of course. But if you’re reading this, I’m going to assume you have access to a PHP-enabled server.

One such technology is the development of the framework. Framework is a framework that allows developers to build an application . There are two types of frameworks , one of which is a web application framework. In this framework there is one type of framework that is widely used by web developers , which is a PHP framework that until now has been growing more than fifteen types to follow the progress of existing technology . With the development of web technology , in addition to facilitate can also cause problems both for the beginners in the world of PHP programming or PHP programmers to choose a framework which is more convenient and effective to use. Therefore , in this study will be a comparison between the two types , namely PHP framework CakePHP framework CodeIgniter framework that is implemented with the creation of websites to display data from a database , so that the two kinds of PHP frameworks can be known benefits and drawbacks to the analysis based on six factors namely in terms of performance , architecture , features - features that are available , the application of Ajax , ORM implementation , and capacity of each library - each framework. 1 / 2 Performance Analysis Framework Codeigniter and CakePHP in Website Creation Refer ences - (http://www.

  • Adopting Web Framework in Web-Application Development
    ADOPTING WEB FRAMEWORK IN WEB-APPLICATION DEVELOPMENT Case: Kehittäjän tieto- ja menetelmäpankki Lahti University of Applied Sciences LAHTI UNIVERSITY OF APPLIED SCIENCES Degree Programme in Business Information Technology Bachelor’s Thesis Spring 2012 Nguyen Minh Thanh Lahti University of Applied Sciences Degree Programme in Business Information Technology NGUYEN, MINH THANH: Adopting web framework in web application development Case: Kehittäjän tieto - ja menetelmäpankki Bachelor’s Thesis of Degree Programme in Business Information Technology, 40 pages, 3 pages of appendices Spring 2012 ABSTRACT Since the web found its true form, it is no longer static web pages without any user’s interaction. During the last few years, web applications have matured to the point that they can compete with full-fledged desktop applications. The support technologies have been growing significantly with the likes of Google web toolkit, web application frameworks, and CMS. This thesis is based on the real application of Tykes, which has been coded by hand in PHP for a few years. The approach is set to improved Tykes’s features and performance. As the result, it shows the benefits of implementing web frameworks in real life works. The action research method is used to answer the research questions in this study, in inductive approach. The researcher’s experience is compared to other relevant published sources. Example source codes are extracted from Tykes. The research results show an expected range. It confirms the positive effects of implementing web framework in web application development. Features which have been tested in Tykes are presented and compared to their originals. Some example source codes are extracted from the application to prove the results.

  • GRADUATION DATABASE SYSTEM by SRIKANTH GADDAM B.E, OSMANIA UNIVERSITY, 2009 a REPORT Submitted in Partial Fulfillment of The
    GRADUATION DATABASE SYSTEM By SRIKANTH GADDAM B.E, OSMANIA UNIVERSITY, 2009 A REPORT Submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Computing and Information Sciences College of Engineering KANSAS STATE UNIVERSITY Manhattan, Kansas 2011 Approved by: Major Professor Dr. Gurdip Singh ABSTRACT Education plays a very important role in molding a person into a good individual by imparting knowledge in all aspects. Globalization has helped the students to go to different countries, attain knowledge and exposure on the culture of that country. Universities receive several hundreds of applications from all over the world to get admission for higher studies. By following the conventional method the faculty of the university and also the applicant will face lot of difficulties in communicating. In conventional method the acceptance or rejection would be generally intimated through post. The applicant will be in complete ignorance during the processing of application. They will be several scenarios where interaction between them is necessary to further process the application. This project is intended to overcome such problems and make the interaction between the staff and applicant smoother. The main objective of the project is to develop a website for Computing and Information Sciences department which manages the data regarding the prospective students as well as students currently enrolled. It can be accessed by prospective students (who wish to join the university), faculty and administrators. Applicant will be notified constantly through email and they can always check their application status online. The role of the administrators is to accept applications sent by prospective students and upload their details such as their GRE, TOEFL scores and their academic records into the database.
