cPanel PHP Upgrade from PHP 7.2 to PHP 7.3

Last modified: July 13, 2022


In cPanel & WHM version 84, we upgraded the internal PHP from version 7.2 to 7.3. This document details the upgrade and the status of known issues.

We tested the internal PHP’s compatibility with packaged applications, such as phpMyAdmin. However, third-party plugin developers must verify that their applications function in the new version.

The php.ini file

cPanel & WHM PHP uses a php.ini file to customize internal PHP settings. The file resides in the following directory:

  • If you edit the cPanel & WHM php.ini file directly, the system will overwrite your changes. Use the PHP section of the Tweak Settings interface to retain changes to cPanel & WHM’s php.ini file.
  • This is the cPanel & WHM php.ini file. For information on EasyApache 4’s php.ini files, read the EasyApache 4 section of our How to Edit Your php.ini File documentation.
