CodeIgniter 2: How to extend CI_Controller multiple times?

Question

I have successfully extended the CI_Controller class by creating a MY_Controller.php which I have placed in the application/core directory.

core/My_Controlle

What you're doing is correct. You just need all of these files in the application/core directory. Here's a post by Phil Sturgeon regarding just this:

The trick is to use the __autoload() function - which Phil describes in his post.
