CodeIgniter extending Controller not working

Question

When I use Class Hello extends CI_Controller in the CodeIgniter framework, everything runs fine. But when I run Class Hello extends Controller, I get the following error:

Fatal error: Class 'Controller' not found in C...... on line 2

Anybody know whats going on? Is the Controller class in CodeIgniter deprecated or something of that nature?

Controllers must extend CI_Controller, that's the name of the controller's core class. — Ben

Hmm, so why in tutorials they reference Controller, and it works on their servers, but when I write the same code and run it on my server it crashes with Fatal Errors? — Michael Grigsby

it appears you have it reversed, Controller was prior to CodeIgniter v2.0 and now it's CI_Controller, here's a dupe post: link

Okay, so it's been replaced? That's what I figured. Thanks man.

Yea, you need to extend CI_Controller, like:

class Hello extends CI_Controller {

If it would have been in versions prior to 2.0.0, your

class Hello extends Controller {

would have worked. Hope it helps
