PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. As of January 2013, PHP was installed on more than 240 million websites (39% of those sampled) and 2.1 million web servers. Originally created by Rasmus Lerdorf in 1995, the reference implementation of PHP is now produced by The PHP Group. While PHP originally stood for Personal Home Page, it now stands for PHP: Hypertext Preprocessor, a recursive backronym.
PHP code is usually executed within the address space of a web server with a PHP interpreter embedded as a module. The server then sends PHP's output to its client. PHP has also evolved to include a command-line interface capability and can be used in standalone graphical applications.
PHP is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.
- For security reasons, we've disabled PHP in student home directories. Students wishing to use PHP for their personal web pages should take the student web server quiz. After you pass the quiz, we'll create an account for you on the student web server so you can integrate PHP into your personal files.
