Can I disable PHP functions on a user level?

When not using PHP-FPM, PHP functions may only be disabled on the system level. They cannot be disabled on a user level. When using PHP-FPM, functions can be disabled per domain with the procedure below.

Procedure

1. Access your server using WHM as the root user
2. Navigate to "Home / Software / MultiPHP Manager"
3. Select the "User Domain Settings" tab
4. Choose the "PHP-FPM Settings" button for the domain you wish to alter
5. In the "Disabled Functions" text area, fill in the name of the function you wish to disable
6. Click "Update" to commit your changes
