PHP is amongst the most widely used multi-paradigm programming languages. It’s pretty popular as it is free software, which can be used to build responsive websites like community websites, e-commerce portals or online teaching portals as opposed to static HTML-based websites. A PHP module should be available on the web server where a PHP-powered website is hosted so that its code can be read. Since there are no license fees for this kind of module and the language offers innumerable possibilities for the web-based applications that you build, there’re hundreds of millions of PHP sites. What is more, there are a huge number of PHP-based scripts, which you can use for your websites without needing to possess any coding expertise. Given the fact that there are different versions of PHP, you must verify if the same version that you used whilst building your website is enabled on the web server as well.
