PHP is the magic that makes your website run. Developers write code in the PHP language and the PHP software sitting on your web server then processes the code each time a page is requested.
The latest stable version of PHP is 8.2.6 . If your server is using this OR the latest revision of an earlier still supported major release ( 8.1.19, 8.0.28 )* then you can give yourself a pat on the back.
The problem is that a large amount of the web is still running on old and in many cases now unsupported revisions of PHP (ie v5.4, v7.0, v7.1, v7.2). Websites running these older versions are not receiving security updates which makes them more vulnerable to hacking.
