PHP Introduction
PHP PHP ─ Introduction PHP started out as a small open source project that evolved as more and more people found out how useful it was. Rasmus Lerdorf unleashed the first version of PHP way back in 1994. PHP is a recursive acronym for "PHP: Hypertext Preprocessor". PHP is a server side scripting language that is embedded in HTML. It is used to manage dynamic content, databases, session tracking, even build entire e- commerce sites. It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server. PHP is pleasingly zippy in its execution, especially when compiled as an Apache module on the Unix side. The MySQL server, once started, executes even very complex queries with huge result sets in record-setting time. PHP supports a large number of major protocols such as POP3, IMAP, and LDAP. PHP4 added support for Java and distributed object architectures (COM and CORBA), making n-tier development a possibility for the first time. PHP is forgiving: PHP language tries to be as forgiving as possible. PHP Syntax is C-Like. Common Uses of PHP PHP performs system functions, i.e. from files on a system it can create, open, read, write, and close them. The other uses of PHP are: PHP can handle forms, i.e. gather data from files, save data to a file, thru email you can send data, return data to the user. You add, delete, modify elements within your database thru PHP. Access cookies variables and set cookies. Using PHP, you can restrict users to access some pages of your website. -

Validating LR(1) Parsers
Validating LR(1) Parsers Jacques-Henri Jourdan1;2, Fran¸coisPottier2, and Xavier Leroy2 1 Ecole´ Normale Sup´erieure 2 INRIA Paris-Rocquencourt Abstract. An LR(1) parser is a finite-state automaton, equipped with a stack, which uses a combination of its current state and one lookahead symbol in order to determine which action to perform next. We present a validator which, when applied to a context-free grammar G and an automaton A, checks that A and G agree. Validating the parser pro- vides the correctness guarantees required by verified compilers and other high-assurance software that involves parsing. The validation process is independent of which technique was used to construct A. The validator is implemented and proved correct using the Coq proof assistant. As an application, we build a formally-verified parser for the C99 language. 1 Introduction Parsing remains an essential component of compilers and other programs that input textual representations of structured data. Its theoretical foundations are well understood today, and mature technology, ranging from parser combinator libraries to sophisticated parser generators, is readily available to help imple- menting parsers. The issue we focus on in this paper is that of parser correctness: how to obtain formal evidence that a parser is correct with respect to its specification? Here, following established practice, we choose to specify parsers via context-free grammars enriched with semantic actions. One application area where the parser correctness issue naturally arises is formally-verified compilers such as the CompCert verified C compiler [14]. In- deed, in the current state of CompCert, the passes that have been formally ver- ified start at abstract syntax trees (AST) for the CompCert C subset of C and extend to ASTs for three assembly languages. -
Continuum & PHP
Continuum & PHP 5.6 UPGRADING FROM PHP 5.3 WISP / LAMP NOTES WISP Platform Where do I get the update from? Windows binaries for PHP 5.6.x can be downloaded from http://windows.php.net/download/ - it should be the non thread safe 32-bit version that is used (x86 Non Thread Safe). What if I’m using WinCache? PHP 5.6 includes it’s own op caching, so if you use WinCache this will need to be uninstalled or commented out (using a semi-colon) in your PHP config. How can I tell if I’m using WinCache? This can be determined by visiting http://{{your-site-URL}}/jadu/maintenance/phpinfo.php in a browser whilst signed into the control centre, or by using apache2ctl -M from the command prompt. If you’re using it then you’ll see it listed there. Do I need driver updates? This depends upon your current set-up; if you don’t already have it you’ll need Microsoft ODBC Driver 11 installing and can then copy php_sqlsrv_56_nts.dll and php_pdo_sqlsrv_56_nts.dll into your PHP install’s ext folder. With these in place you’ll then need to update your php.ini to point at these in place of the PHP 5.3 equivalents. LAMP Platform In most cases this will mean you’re using CentOS or Red Hat as these are the supported Linux distributions for the Continuum platform. How do I do update PHP on CentOS/RHEL 6.x? What you’ll need to run will differ slightly depending on which distribution (CentOS vs. -

ACCELERATION of STRUCTURED and HETEROGENEOUS CONFIGURATION of the APPLICATIONS1 Alexander P
ACCELERATION OF STRUCTURED AND HETEROGENEOUS CONFIGURATION OF THE APPLICATIONS1 Alexander P. Penev, Dimcho S. Dimov, Dobromir P. Kralchev This paper treats some aspects of configuring applications, libraries, and object classes. We are proposing heterogeneous and structured approach, to define para meters of the systems, based on hierarchies of attribute-value (pairs) with addi tional metadata. This approach uses multiple levels and multiple formats of the configuration sources (files, databases, etc.). We are proposing a method for caching of configuration sources, which are security insensitive, in order to ac celerate them. 1. INTRODUCTION The present-day applications more and more often pay attention to contriv ances for settings from system administrators (super users) and users. There fore, usually one of a basic subsystem of the core of every application is a con figuration subsystem. Configuring is a process of setting some elements parameters of the system (functions, methods, objects, classes, modules, libraries, subsystem, dynamic loaded modules, etc.). There are many [2-13] approaches for configuring applications and libraries. They have pros and cons. Usually every library, framework, or application has its own approach to configure (and its own file format for saving configuration). The basic differences among them are configuration file format, number, and organization of the files, as well as their location in the system. For the needs of the developed from the authors applied system, OpenF [1], an approach is used which is based on the below described characteristics of the methods for configuring. This approach is open for integration of almost all aspects of the other systems. In addition, a configuration files hierarchy, and metadata are used. -

Installing and Configuring PHP
05 6205 CH03.qxd 11/20/03 11:27 AM Page 51 CHAPTER 3 Installing and Configuring PHP In the last of the three installation-related chapters, you will acquire, install, and configure PHP and make some basic changes to your Apache installation. In this chapter, you will learn . How to install PHP with Apache on Linux/Unix . How to install PHP with Apache server on Windows . How to test your PHP installation . How to find help when things go wrong . The basics of the PHP language Current and Future Versions of PHP The installation instructions in this chapter refer to PHP version 4.3.3, which is the current version of the software. The PHP Group uses minor release numbers for updates containing security enhancements or bug fixes. Minor releases do not follow a set release schedule; when enhancements or fixes are added to the code and thor- oughly tested, the PHP Group will releases a new version, with a new minor version number. It is possible that by the time you purchase this book, the minor version number will have changed, to 4.3.4 or beyond. If that is the case, you should read the list of changes at http://www.php.net/ChangeLog-4.php for any changes regarding the installation or configuration process, which makes up the bulk of this chapter. Although it is unlikely that any installation instructions will change between minor version updates, you should get in the habit of always checking the changelog of software that you install and maintain. If a minor version change does occur during the time you are reading this book, but no installation changes are noted in the 05 6205 CH03.qxd 11/20/03 11:27 AM Page 52 52 Chapter 3 changelog, simply make a mental note and substitute the new version number wherever it appears in the installation instructions and accompanying figures. -
