PHP: Hypertext Preprocessor (or simply PHP) is an open-source programming language used for web development, created by Rasmus Lerdorf. It is an HTML-embedded scripting language for creating dynamic web sites. The standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge. PHP 7.3 is the latest stable version of PHP.
