In this article, you will get information about different web applications’ compatibility with different PHP versions available on Cloudways. Your new server is configured to use PHP 7.4 by default. You can always upgrade to the latest version, e.g., PHP 8.1, as per your requirements. Downgrading the PHP version has some limitations, so you can view which PHP versions you can upgrade or downgrade to currently.
Important Announcement for PHP Older Versions
Available versions of PHP include PHP 5.6, 7.0, 7.1, 7.2, 7.3, 7.4, 8.0, and 8.1 but 5.6, 7.0, 7.1, 7.2, and 7.3 versions are deprecated as of August 15th, 2022. As a result, new and existing servers with default PHP 7.4 or newer versions can upgrade or downgrade to non-deprecated versions (PHP 7.4, 8.0, and 8.1) but can not downgrade to deprecated versions (PHP 5.6, 7.0, 7.1, 7.2, and 7.3).
Existing servers with deprecated versions will continue to work for the time being. The deprecated versions will reach the end of life on February 28th, 2023; therefore, you are requested to upgrade to the latest version. Please refer to Cloudways deprecation process and policy for more details.
