PHP. Scripting language created in 1994 PHP is a general-purpose scripting language geared towards web development.[8] It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1993 and released in 1995.[9][10] The PHP reference implementation is now produced by the PHP Group.[11] PHP was originally an abbreviation of Personal Home Page,[12][13] but it now stands for the recursive initialism PHP: Hypertext Preprocessor.[14] 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 a variety of operating systems and platforms.[17] The PHP language has evolved without a written formal specification or standard, with the original implementation acting as the de facto standard that other implementations aimed to follow.

This page provides a list of keyboard shortcuts which you may find useful.
How to use a keyboard shortcut Traditionally, keyboard shortcuts are written like so: Alt + F1. This means that you should press the Alt and F1 keys simultaneously.
