PHP Requirements

We strongly suggest using at least PHP 5.6. PHP itself doesn't support any versions lower than 5.6. Click here to see more details on currently supported PHP versions or see the "Supported Versions" diagram below.

Currently supported PHP versions

Any version of PHP before 5.6 doesn’t have security updates and will not keep your site safe.

As you can see from the diagram, any release of PHP lower than 5.6 is marked as "End of life". According to the PHP website, a PHP release marked as "End of life" is:

A release that is no longer supported. Users of this release should upgrade as soon as possible, as they may be exposed to unpatched security vulnerabilities.

The official Joomla recommendation is PHP 5.6 or higher. Click here to see Joomla's recommendations.
