CodeIgniter - Controller Double Inheritence Breaking When Deploying To Server - php

Question

I really need some guidance here as this issue is pretty confusing and extremely different to understand for a beginner like myself.
I am running a WAMP server with the latest CI version.
In core/MY_Controller.php I have:
public GeneralController extend CI_Controller {
public GeneralController() {
parent::__construct();
// Does some stuff
}
}
public AuthenticatedController extend GeneralController {
public AuthenticatedController() {
parent::__construct();
if(!loggedIn()) redirect("/login");
// Does some stuff
}
}
public UnauthenticatedController extend GeneralController {
public UnauthenticatedController() {
parent::__construct();
if(loggedIn()) redirect("/home");
// Does some stuff
}
}
My login controller is:
class Login extends UnauthenticatedController {
So basically if they are logged in and load "/login" they will be routed to "/home".
This works perfectly on my local environment.
Once I upload it to my server and navigate to "/login" I get an infinite loop. After debugging I figured out that the Login controller loads AuthenticatedController instead of UnauthenticatedController so it keeps redirecting back to "/login" infinitely.
Well, now the inheritance is broken for some reason so I need to check if it calls both Auth and Unauth controllers. Nope. Just calls Auth even though it extends UnauthenticatedController.
I am at a loss here, I've tried everything I can imagine but as a new php programmer I thought I would pick some of your brains on things to try!
Thank you!
Solution:
Check your production server php version vs. local

Answer 1

I also had this problem with extending core classes. My problem was that is was working on my local server, but not on my production server. I was receiving the 404 error in production, and only on my controllers that used the class extensions. After some research I noticed that my local server was running php version 5.3.x, while my production server was running 5.2.x. To fix this I had to upgrade my production server to 5.3.
To find out what version of php your site is using, place this command in your view:
<?php echo phpversion() ?>
