How to Enable or Disable PHP Extensions in cPanel

To Enable or Disable PHP Extensions in cPanel is a very common task when you are running WordPress, Laravel, or any PHP-based application. Some plugins and frameworks require specific PHP extensions to function properly, while others may conflict with unused modules. 

In this guide, we will show you how to enable or disable PHP extensions in cPanel using simple, beginner-friendly steps.

Quick Answer:

To enable or disable PHP extensions in cPanel, log in to cPanel, open Select PHP Version, choose your PHP version, go to the Extensions tab, and check or uncheck the required modules. The changes apply instantly and do not require a server to restart. 

What Are PHP Extensions and Why Do They Matter? 

PHP extensions are libraries that add extra functionality to PHP. Without the required extensions, your website may show errors, fail to load features, or break completely. 

Common use cases: 

• WordPress plugins requiring mysqli, curl, or zip 
• Laravel needing mbstring, openssl, or pdo 
• Payment gateways using soap or json 

Keeping only required PHP extensions enabled helps improve performance, security, and stability.
