PHP is among the most commonly used class-based programming languages. It is pretty popular since it’s free software, which can be used to build interactive websites such as community web portals, e-stores or online teaching websites instead of static HTML-based websites. A PHP module must be activated on the web server where a PHP-powered site is hosted so that its PHP code can be ‘decrypted’. Because there aren’t any license charges for this sort of module and the language itself provides limitless possibilities for the applications that you create, there are 100s of millions of PHP-driven websites. In addition, there’re an immense number of PHP-based scripts, which you can use for your sites without having to possess any programming expertise. As there are different PHP versions, you need to ensure that the very same version that you used while building your site is installed on the server as well.
