Latest PHP Version Supported By XenForo


Well-known member
Might be a noob question: But I want to know which is the latest version of PHP supported by Xenforo? I wish to upgrade php on our server (assuming it will bring performance and security enhancements) and want to know which PHP version should I ask our server admin to install so that xenforo works without any problem?

Is upgrading worth it? Apart from what's in their release note - is there any noticeable improvement if we go from PHP 5.3 -> 5.4?

yes worth it = reduced PHP related memory usage can be as much as up to 50% reduction in some cases
