General Information – PHP

PHP is a server-side scripting language that is now used for general use and especially in website development.

A lot of websites these days use PHP, such as any websites using WordPress, Joomla or Drupal CMSs.

Furthermore, as with any software, app or programming language, it is imperative to keep this up to date, but how do you know which is the latest version? And what are the perks of upgrading?

This guide should help with some basic knowledge of PHP with some great resources you can use to get some more information.

Our hosting offers versions 5.6 – 7.3 on most of our servers.
