PHP: Hypertext Preprocessor (web, programming) (PHP) An Open Source, server-side, cross-platform, scripting language used to create dynamic web pages.
PHP can be embedded in HTML using special tags like: <?php echo '<p>Hello World</p>'; ?>
This is stored in a file with a ".php" extension. The web server passes the file to the PHP interpreter which executes the code in the <?php ... ?> tags. The tagged code is then replaced with its output, typically ordinary HTML, in the response sent to the web browser. PHP is a recursive acronym. Latest version: 5.3.2 2010-03-04, as of 2010-03-20.
