This document lists the options to use per user php.ini under the environment of hosting control panel(cPanel/WHM, Plesk, DirectAdmin, etc) + LiteSpeed Web Server(LSWS).
Put something like “PHPRC=$VH_ROOT” in lsphp environment (Web Admin Console→Server→External App→lsphp5→Edit→Environment).
After that restart the litespeed server from back-end(/etc/init.d/lsws restart).
And put the custom php.ini in the following path /home/<user>/
Make sure permission of php.ini file is readable by suEXEC user
PHPRC is to use user-defined php.ini ONLY.
$VH_ROOT refers to user’s home directory which applies to every vhost(user account) under one main account.
