PHP 7.4 End of Life Resources

PHP. 7.4 is coming to an end of life on October 2022. You have a few options to keep your application secure.

Keeping your application secure and up to date is an important part of application maintenance.

Due to end of security compliance for PHP 7.4  Acquia Cloud applications will be upgraded to PHP 8.0  automatically as part of regular maintenance, as communicated to customers by email.

  • Do you need more time? Acquia is offering the option to purchase extended Long-Term Support for PHP 7.4 for Cloud Platform Enterprise, Acquia Site Factory applications, and Cloud Platform Professional applications in an effort to provide additional time for our customers to make the transition to a supported version of Drupal and to PHP 8.x. Entitlement must be in place by October 1st 2022.
  • Do you need assistance in the PHP Upgrade? Contact your Account manager about Acquia's Professional Services PHP Upgrade Assistance package. Acquia Professional Services can assist in upgrading your Drupal Core version and PHP version to a security compliant version. 
  • Do you want to upgrade yourself? If you choose to upgrade your PHP version yourself, Acquia recommends  you should upgrade your non-production applications to test for any incompatibilities in your application. We recommend beginning with your non-production upgrades as soon as possible to ensure you have time to test, prior to upgrading your production application. Once you have resolved any incompatibilities, upgrade your production environment before the end-of-life deadline. See preparing for your php upgrade tutorial for instructions on changing your PHP version.

If your application is facing compatibility issues that are preventing your upgrade to PHP 8.x or higher, Acquia recommends upgrading your application's Drupal version to ensure that your application remains secure and functional. If you are in need of assistance to upgrade your Drupal application, please contact your account manager in order to discuss ways our Professional Services team could provide additional support through an engagement. 

PHP 8.0 compatibility by Drupal Core version

    Applications using Drupal 7.x will need to upgrade their Drupal core to Drupal 7.79 or higher in order to upgrade from PHP 7.4 to PHP 8.0. Some modules designed for Drupal 7 may be incompatible with PHP 8.0. More information regarding Drupal 7.x compatibility with PHP 8.0 please see the documentation available on Drupal.org

    See What does it take to upgrade from Drupal 7 to Drupal 9

    As Drupal 8.x has reached its end of life with Drupal.org, no version of Drupal 8.x is compatible with PHP 8.0. If an application is still utilizing Drupal 8.x, it will need to be upgraded to Drupal 9.1 or higher in order to upgrade from PHP 7.4 to PHP 8.0 or you will need to purchase long-term support for PHP 7.4. Please contact your account manager in order to discuss these options as needed.

     

     Drupal 9.x customers we recommend upgrading your Drupal core to Drupal 9.3.0 or higher prior to implementing PHP 8.1. More information can be found here.

    For customers who intend to upgrade their Drupal core to Drupal 10 in the future Acquia recommends updating to PHP 8.1 over PHP 8.0 as PHP 8.1 or higher is required to complete upgrading your Drupal core to Drupal 10. More information can be found here.

    Troubleshooting Upgrading PHP

      As a general rule we do not recommend skipping versions. Upgrade PHP to 8.0 and then to 8.1.

      • ASF does not have PHP 8.1 support (yet) so do not upgrade to PHP 8.1 yet.
      • For a customer using Acquia Pipelines and doing this upgrade, we recommend trying to run pipeline using 8.0 first, before trying PHP 8.1. #4373 [pipelines] use Composer 2 and PHP 8

      The amount of time it takes to upgrade can change depending on how many dependencies your repository has. If you feel the upgrade is taking too long you can file a support ticket through your cloud interface. 

      Order of operations are important. Check your logs to make sure your dependencies are updating in the correct order. 

      Acquia offers PHP LTS until you are ready to upgrade to PHP 8.x.

      BLT 12 added Drupal 9 support while BLT 13 updated pipelines for PHP 8 and Composer 2.The specific pipelines commit added in BLT 13 is at https://github.com/acquia/blt/pull/4373.For a customer using Acquia Pipelines and doing this upgrade, I would definitely try running pipeline using 8.0 first, before trying 8.1.

      Use the dev version of Acquia Purge.

      $ composer require 'drupal/purge:[email protected]'

      In order to continue to use Drush you must use a version of Drush that is compatible with PHP 8.x. See Drush's documentation on Drush and PHP compatibility

      Acquia recommends you require a site-local Drush as part of your codebase, not your home directory, and run your commands with a specific major version of Drush. It is dangerous to run the globally-installed version of Drush because the behavior of your cron jobs, Cloud Hooks, or other automated scripts may change unexpectedly when a new version of Drush becomes the default See Drush's documentation on how to install drush with composer. 

      composer require drush/drush

       

      Drush and PHP compatability

      D8 is not compatible with PHP 8,  so yes you will either have to upgrade Drupal version and PHP version or purchase PHP 7.4 LTS.
