PHP, which is an initialism for PHP: Hypertext Preprocessor, is among the most popular coding languages that are available out there. Any site or Internet application created with PHP will run on a given server provided that a PHP module is activated, which renders the language truly universal and it is not very surprising that there are actually a few million servers that support it and 100s of millions of PHP websites hosted on them. PHP is preferred over HTML because of the fact that it allows you to set up a responsive site with a huge number of options. A PHP-based community site, for example, will display unique content to each user although the URL won’t change. In contrast, HTML websites are static and the page content itself can be updated only manually. Like any other software program, PHP has different versions and the one that was used while building a certain website must be available on the server so that the site can run properly.
