PHP is a computer scripting language originally designed for producing dynamic web pages.[1] The name PHP is a recursive initialism for PHP: Hypertext Preprocessor.
PHP is used mainly in server-side scripting, but can be used from a command line interface or in standalone graphical applications. Textual User Interfaces can also be created using ncurses.
The main implementation is produced by The PHP Group and released under the PHP License. This implementation serves to define a de facto standard for PHP, as there is no formal specification. The most recent version of PHP is 5.2.5, released on 8 November 2007. It is considered to be free software by the Free Software Foundation.[2]
