The official and published timelines for new and end-of-life versions of PHP can be found at: https://www.php.net/supported-versions.php

• DoIT Web Hosting typically provides support for new versions of PHP within one month of their release.
• Customers are responsible for making sure their PHP applications are up-to-date, secure, and can run on these supported frameworks.
• DoIT Web Hosting cannot host applications that are incapable of running on an actively supported version of PHP and will reach out to customers to advise on a path forward
