What are the best practices for managing PHP settings in a Plesk environment to avoid conflicts with existing configurations?

When managing PHP settings in a Plesk environment, it is important to avoid conflicts with existing configurations by carefully reviewing and adjusting the settings. One best practice is to create a custom PHP configuration template in Plesk and apply it to individual domains or subscriptions as needed. This allows for granular control over PHP settings without affecting other domains or subscriptions.
