Sometimes you will want to or need to make changes to your php.ini file. For example, suppose you want to change a value within the PHP disable_function section. See PHP Core PHP.INI Disable Function Option.
Typically, you would go into WHM => MultiPHP INI Editor and go to Editor Mode and then select the PHP version you wish to change the disable_functions section for. Then you would find the disable_function area and adjust as necessary.
But what if you're using PHP-FPM? In that case, you would need to follow an entirely different method. Instead, you would then go to WHM => MultiPHP Manager and select the Edit PHP FPM link to the account's far right side.
Then scroll down to the disable_functions section and either Add a new function to disable or click on the Edit function list and remove any functions you no longer wish to have disabled.
Finally, click Save Configuration.
