How to access the php.ini from cPanel?

I want to change the limit of the PHP POST array from 1000 to 6000. Is there any way to do that? I searched it and found that I should change some variables in php.ini but the problem is that I did not find the directory of the file in my cPanel: ``` Your server's php.ini file is located at /usr/local/lib/php.ini. ``` This line is from the CPanel documentation but i could not find this directory in my cpanel even after i show the hidden files???? can anybody help me locating this file?
