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. Here you can also make additional adjustments to other common settings such as max_input_vars, max_input_time, memory_limit, post_max_size and upload_max_size. You can also modify these values for specific users or domains using the cPanel => MultiPHP INI Editor interface.
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.
The other additional options (memory_limit, post_max_size, etc...) listed above cannot be modified in this section.
