The currently supported releases of PHP are 8.0, 8.1, and 8.2. 8.0 will reach its end of life on November 26, 2023.
Units who have their own web servers are strongly urged to keep them up-to-date with at least PHP 8.0, and ideally a later version. Any OIT Web Hosting site can be easily switched to any of the supported PHP versions through the Plesk control panel. Please note that upgrading PHP may break some applications, so you should test carefully and be prepared to roll back to an older version of PHP if needed until you can fix problems that arise. For this reason, it is best to start your testing early, long before the version of PHP that you are running reaches its end-of-life.
Helpful Tips and Information
- Version Compatibility
- Drupal 10 is core compatible with PHP 8.1 and PHP 8.2
- Drupal 9.4+ is core compatible with PHP 8.0 and 8.1
- Drupal 7.79 or later will support PHP 8.0
- Important: While the core of Drupal 7 is compatible with PHP as described above, many modules for Drupal 7 may not be receiving updates and thus may not be compatible with these later versions of PHP.
- Important: Drupal 7 itself will reach its end-of-life on November 28, 2022. If you are still running a Drupal 7 site, you should start planning now to upgrade it to Drupal 9 or 10 or migrate it to another content management system (e.g. Sites @ Georgia Tech).
- "Core compatible" only means that the core of Drupal is compatible with the listed PHP version. All third-party and custom modules and themes must be separately checked, tested, and updated as needed.
