PHP is among the most widely used multiparadigm programming languages. It’s very popular as it is free software, which you can use to build interactive websites like community portals, online shopping portals or online learning portals rather than static HTML sites. A PHP module should be present on the server where a PHP-powered site is hosted so that its source code can be interpreted. Since there are no license fees for this type of module and the language itself offers unlimited options for the applications that you set up, there are 100s of millions of PHP-driven sites. In addition, there’re a huge number of open-source PHP scripts, which you can use for your websites without the need to have any coding knowledge. Since there’re a couple of PHP versions, you should verify whether the same exact version that you used while setting up your website is available on the server too.
