PHP (Hypertext Preprocessor)
PHP is a script
language and interpreter that is freely available and used primarily on Linux
Web servers. PHP, originally derived from Personal Home Page Tools, now stands for PHP:
Hypertext Preprocessor, which the PHP FAQ describes as a "recursive acronym."
PHP is an alternative to Microsoft's Active
Server Page (ASP) technology. As with ASP, the PHP script is embedded within a Web page along
with its HTML.
Before the page is sent to a user that has requested it, the Web server calls PHP to interpret and
perform the operations called for in the PHP script.
An HTML page that includes a PHP script is typically given a file name suffix of ".php" ".php3,"
or ".phtml". Like ASP, PHP can be thought of as "dynamic HTML pages," since content will vary based
on the results of interpreting the script.
PHP is free and offered under an open
source license.
