PHP is among the most widely used open-source web programming languages. It’s pretty popular since it is free software, which can be used to set up responsive sites such as social networks, online shops or online teaching websites rather than static HTML-based sites. A PHP module should be available on the server where a PHP-driven site is hosted so that its source code can be read. As there aren’t any license taxes for this type of module and the language itself offers infinite options for the Internet applications that you set up, there are hundreds of millions of PHP sites. What is more, there are a myriad of open-source PHP scripts, which you can use for your websites without the need to possess any programming experience. Given the fact that there are a few versions of PHP, you should make certain that the same version that you used whilst setting up your site is enabled on the web server too.
