PHP is amongst the most commonly used open-source server-side coding languages. It’s extremely popular as it’s free software, which can be used to create interactive sites such as social networking websites, Internet shops or online teaching websites as opposed to static HTML websites. A PHP module must be enabled on the server where a PHP-driven site is hosted so that its source code can be ‘deciphered’. As there are no license taxes for this type of module and the language itself offers countless possibilities for the web-based apps that you create, there’re hundreds of millions of PHP-powered websites. On top of that, there’re plenty of open-source PHP-based scripts, which you can use for your websites without needing to possess any coding abilities. Since there are a number of PHP versions, you have to verify whether the same version that you used whilst setting up your site is installed on the web server as well.
