Different applications need different PHP versions; you can switch yours easily.

1. Log in to cPanel.
2. Go to Software > Select PHP Version (or MultiPHP Manager).
3. Choose your domain (in MultiPHP Manager) and pick the PHP version from the dropdown.
4. Click Apply.

Note: Always use a currently supported PHP version for security and speed. If your site breaks after a change, switch back and check with the application's requirements.
