PHP, which stands for PHP: Hypertext Preprocessor, is one of the most popular web programming languages available out there. Any website or web application created using PHP will run on a given web server on the condition that a PHP module is enabled, which renders the language absolutely universal and it is not really a huge surprise that there are a few million web servers that support it and hundreds of millions of PHP websites hosted on them. PHP is preferred over HTML owing to the fact that it permits you to develop a dynamic serving website with a multitude of features. A PHP-based community web portal, for instance, will serve different content to each user despite the fact that the URL will not change. In contrast, HTML sites are static and the page content can be edited only manually. Like any other piece of software, PHP has several versions and the one that was used while building a given website must be activated on the web server in order for the site to behave flawlessly.
