PHP is one of the most commonly used programming languages. It is very popular as it is free software, which can be used to develop interactive websites such as community sites, Internet shops or school websites as opposed to static HTML-based websites. A PHP module should be enabled on the web server where a PHP-driven website is hosted so that its source code can be read. Because there are no license taxes for this kind of module and the language offers countless options for the web applications that you create, there’re 100s of millions of PHP-powered websites. Furthermore, there’re lots of open-source PHP-based scripts, which you can use for your sites without needing to possess any coding knowledge. Considering the fact that there’re a couple of PHP versions, you need to verify whether the exact same version that you used while building your website is activated on the server as well.
