What is PHP?
This is a programming language which enables your website to be more dynamic.
PHP is a HTML embedded scripting language that lets you create dynamic web pages. It is an open source, server-side, and cross-platform scripting language. PHP-enabled web pages are treated just like regular HTML pages and you can create and edit them the same way you normally create regular HTML pages.
Each programming language has its own benefits. Find out more at www.php.net
