PHP 5 has reached end of support and will be
deprecated
on January 31, 2026. After deprecation, you won't be able to deploy PHP 5
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing PHP
5 applications will continue to run and receive traffic after their
deprecation date. We recommend that
you
migrate to the latest supported version of PHP.
