Update PHP extensions using PHP Selector – cPanel

Login to cPanel.
Tutorial: login from the Client Area or the direct link.

Find the Software section and click the Select PHP Version link.

Change the PHP version for this cPanel
– click the current version and select the required version from the drop-down and then click Set as Current.

A PHP extension (sometimes also called PHP Module), extends the PHP language with more functions.
For example, the Imagick extension – external link opens in a new window provides a range of PHP functions relating to image manipulation.
If you attempt to use any of these functions without activating this extension then your pages will return an internal server error.

Depending on the PHP version you select you will see the PHP Extensions available, with the system default modules for that version selected.
Selecting unnecessary PHP extensions to load at run-time can adversely affect the performance of your website because the server has to open more files to process your scripts.
This functionality should be used with care.

Select which extensions you want to enable for the current PHP version:
– To enable an extension, select the check box next to the extension name.
– To disable an extension, clear the check box next to the extension name.


Example:
Under letter T – timezonedb
Select the check box next to timezonedb and activate the module.

Selections are saved automatically!
Success
Module timezonedb saved

To reset the extension list to the default configuration, click Reset to default in the top right corner.
