PHP versions below 7.2 to reach end-of-sale

March 20, 2024

As part of our continued effort to provide the latest and best in secure software, PHP versions 7.1 and below will reach end-of-sale (EoS) on May 15, 2024. This means that sites created after May 15 will not be able to change their PHP version to PHP 7.1, 7.0, or any version of PHP 5. Sites created with custom upstreams using EoS PHP may also have unexpected behavior upon site creation.

Sites already running PHP 5, PHP 7.0, or PHP 7.1 will continue to run even after May 15.

PHP 7.1 was declared end-of-life (EoL) by the PHP Foundation on November 30, 2020, more than three years ago. PHP 5.6 reached EoL on December 31, 2018, more than five years ago. EoL software does not receive security or feature updates, and could expose sites to attack if any vulnerabilities or exploits are discovered.

Action required

Customers using custom upstreams with a PHP version less than 7.2 should update their custom upstreams by May 15 to avoid disruption. The current supported versions of PHP are 8.1, 8.2, and 8.3. Pantheon currently recommends at least PHP 8.1 for all production sites.
