How to update PHP Versions, Modules, and Settings in cPanel
This guide is for our Personal, Business, Premium and Reseller plans, as well as VPS and Dedicated Servers with CloudLinux.
If you're on a WHM/cPanel VPS or Dedicated Server without CloudLinux, click here for a guide on changing PHP settings.
What is PHP and why does it need to be updated or configured?
PHP is a scripting language that is generally used for websites. For web servers to execute the PHP code, they require a PHP interpreter to read and translate the PHP code for the server to understand and execute.
Over time, vulnerabilities are patched up and improvements are made to the PHP code base which requires PHP interpreters to also be updated.
We generally recommend that you keep PHP updated to the latest versions for improved performance and security of your website - follow this link here
to find the latest supported versions of PHP.
Are there any risks in changing my PHP version?
Depending on how your website is coded, there is a chance that your website will not work on a different PHP version - newer versions of PHP often remove older functions and/or change how older functions operate to improve performance and security.
We recommend updating the PHP version, one version at a time and testing after every update - if the website loses functionality, then roll back the PHP version and update your website so it will be compatible with the new version.
If you are not confident with updating PHP, we advise getting in contact with your website developer for further assistance.
