PHP: Hypertext Preprocessor



(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:

 Hello World

'; ?>

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.
