PHP is amongst the most commonly used open-source programming languages. It’s very popular as it’s free software, which you can use to create interactive sites like community web portals, web shops or online learning portals rather than static HTML-based sites. A PHP module must be installed on the server where a PHP site is hosted so that its source code can be ‘deciphered’. Because there are no license charges for this sort of module and the language offers countless options for the applications that you create, there’re hundreds of millions of PHP-driven sites. What is more, there are plenty of PHP scripts, which you can use for your websites without the need to have any coding experience. Since there’re a handful of PHP versions, you have to confirm whether the same version that you used whilst creating your website is available on the server too.
