PHP, which is an abbreviation for PHP: Hypertext Preprocessor, is among the most commonly used scripting languages available out there. Any website or Internet application built with PHP will run on a given server on the condition that a PHP module is activated, which renders the language truly universal and it is not surprising that there are actually several million web servers that support it and 100s of millions of PHP-driven websites hosted on them. PHP is preferred over HTML because it enables you to set up a dynamic site with a plethora of options. A PHP-based community site, for instance, will serve unique content to each user regardless of the fact that the page URL won’t change. By contrast, HTML sites are static and the page content can be edited only manually. Just like any other software program, PHP has several versions and the version that was used whilst setting up a certain website must be enabled on the web server so that the site can run faultlessly.
