For Core Controller,
As far as I know they are built-in within CodeIgniter.
But you can replace and extend them.
The common extension for core controller is MY_Controller.
The purpose of MY_Controller is to handle multiple sub-controllers.
As for ordinary controller,
It's a user custom controller which reside in the /controller/ directory.
I think you already knew what an ordinary controller looks like.
The good thing is you can extend the Core Controller using MY_Controller
and use it for your ordinary controller in the /controller/ folder.
Any one has impressive explanation than mine is welcome?
