PHP Compatibility
Data Sources
The raw data for this chart is based on the “minimum required PHP version” and the “latest tested version of PHP” for each WordPress version.
This chart displays the supported PHP versions.
History
For long time WordPress officially released only the minimum PHP version required to run WordPress. The practice begin with the release of WordPress 2.0.
There was never a maximum PHP version, it was always assumed that WordPress will work on the latest PHP version available at the time of each WordPress release.
At some point, when automated tests added, we could retrieve the latest tested version of PHP for each WordPress release.
