Switching PHP versions per site
PHP 8.2, 8.3, and 8.4 are all available; here's how to switch safely.

Shared sites can run PHP 8.2, 8.3, or 8.4 independently — you don't have to commit your whole account to one version.
Change the version from Apps → your-site → Runtime → PHP. The change takes effect immediately; PHP-FPM workers restart with zero customer-facing downtime.
Before changing the major version, run the upgrade test from the same panel. We boot a temporary worker, replay 50 of your recent request URIs against it, and report any errors. Most WordPress and Laravel sites can move from 8.2 → 8.4 cleanly; older themes occasionally hit deprecation notices.
If you do hit issues, roll back is one click. We keep the previous worker configuration warm for 24 hours so the rollback itself is instant.
