Best Seven factors of Web Development in PHP
PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. Originally created by Rasmus Lerdorf in 1994, the PHP reference implementation is now produced by The PHP Group.
PHP code may be embedded into HTML code, or it can be used in combination with various Web template systems and web frameworks. PHP code is usually processed by a PHP interpreter implemented as a module in the web server or as a Common Gateway Interface (CGI) executable. The web server combines the results of the interpreted and executed PHP code, which may be any type of data, including images, with the generated web page. PHP code may also be executed with a command-line interface (CLI) and can be used to implement standalone graphical applications.
Learning PHP: There are several php training institute and they teach web development using php. Mostly web development companies works on PHP. Learning PHP is easy as compare to JAVA. Web development is easy in PHP.
Implementation: The original, only complete and most widely used PHP implementation is powered by the Zend Engine and known simply as PHP. To disambiguate it from other implementations, it is sometimes unofficially referred to as “Zend PHP”. The Zend Engine compiles PHP source code on-the-fly into an internal format that it can execute, thus it works as an interpreter.
Licensing: PHP is free software released under the PHP License, which stipulates that:
Products derived from this software may not be called “PHP”, nor may “PHP” appear in their name, without prior written permission from firstname.lastname@example.org. You may indicate that your software works in conjunction with PHP by saying “Foo for PHP” instead of calling it “PHP Foo” or “phpfoo”
Development and Community: PHP includes various free and open-source libraries in its source distribution, or uses them in resulting PHP binary builds. PHP is fundamentally an Internet-aware system with built-in modules for accessing File Transfer Protocol (FTP) servers and many database servers, including PostgreSQL, MySQL, Microsoft SQL Server and SQLite (which is an embedded database), LDAP servers, and others. Numerous functions familiar to C programmers, such as those in the stdio family, are available in standard PHP builds.
Installation and Configuration: There are two primary ways for adding support for PHP to a web server — as a native web server module, or as a CGI executable. PHP has a direct module interface called Server Application Programming Interface (SAPI), which is supported by many web servers including Apache HTTP Server, Microsoft IIS, Netscape (now defunct) and iPlanet.
USE: PHP is a general-purpose scripting language that is especially suited to server-side web development, in which case PHP generally runs on a web server. Any PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content or dynamic images used on websites or elsewhere.
Security: There are advanced protection patches such as Suhosin and Hardening-Patch, especially designed for web hosting environments.
There are certain language features and configuration parameters (primarily the default values for such runtime settings) that make PHP applications prone to security issues. Among these, magic_quotes_gpc and register_globals configuration directives are the best known; the latter made any URL parameters become PHP variables, opening a path for serious security vulnerabilities by allowing an attacker to set the value of any uninitialized global variable and interfere with the execution of a PHP script. Support for “magic quotes” and “register globals” has been deprecated as of PHP 5.3.0, and removed as of PHP 5.4.0.
