Step 6: Once you have chosen the domain you want to modify PHP variables on, the PHP directive list will appear.
With this list, you have the option to increase or decrease the variables on settings like max_input_time, max_execution time_, memory_limit, post_max_size, and upload_max_filesize.
Be sure to click the blue Apply button at the bottom if you make any changes to these settings!
