Update to the Latest PHP Version
Run the newest PHP version your Joomla release supports. It is faster and lighter: Joomla 5 needs PHP 8.1 or newer, Joomla 6 needs PHP 8.3 or newer.
Always use the latest PHP version compatible with your Joomla installation. The latest versions of PHP are not only faster but also use fewer computing resources and therefore less energy. Joomla 5.X requires at least PHP 8.1 but recommends PHP 8.3 (actively supported till December 2025)
