Question

I have 3 controllers doing exactly the same, calling the same models and views. But I have to create three different controllers purposely.

Is there any way of extending one controller into another? Or calling a controller function into another? Or should I create a library for it and use it in my controllers?

Please suggest me the best approach.

I am not that familiar with CodeIgniter, but you can try to create a base class controller that contains the functionality you need, and subclass this controller for the actual controllers:

// CI2+ in core dir, libraries dir for CI < 2
class MY_Controller extends CI_Controller {

    public function index()
    {
        // Your functionality
    }
}

class ActualController extends MY_Controller 
{
}
