PHP: Hypertext Preprocessor

(World-Wide 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. This generates ordinary HTML to send to the web browser.

PHP is a recursive acronym.
