Admin roles in admin panel - PHP & MySQL

Source code:

Let's say you have an admin panel of your website where you can manage your website's data. Now you want to have a functionality where you can create sub-admins with access to limited features. For example, one admin can manage posts (add, edit and delete), another admin can manage customers, another admin can manage employees, and so on. And they all will be managed by super admin.
