php - Codeigniter Class and filename case sensitive on Linux (centos)

Question

I am running into a case-sensitive problem that I'm not able to wrap my head around it appears.

This is what my file structure looks like. I am only entering the directories that I am working with, but I am in fact using a full-install of CI3.

/application
    ....
    /controllers/
        application_controller.php
    /core/
        MY_Controller.php
        Public_controller.php
    ....
    /models/
        Application_model.php
    ....

Here is what the class definition syntax looks like:

/application/core/My_Controller.php

class MY_Controller extends CI_Controller
{
    function __construct()
    {
        parent::__construct();
    }
}

/application/core/Public_Controller.php

class Public_Controller extends MY_Controller
{
    function __construct()
    {
        parent::__construct();
    }

    // Application logic here...
}

/application/controllers/application_controller.php

class Application_controller extends Public_Controller
{

    public function __construct()
    {
        parent::__construct();
    }

    // Application logic here...
}

Reading the docs, I see that I should name my classes something like:

Foo_Controller.php

Then i've always (thought) that the class definition should match the file name. So:

class Foo_Controller extends Bar_Controller {
    ....
}

Then I either get a 500 error, or I get no errors, and a white page. When I work locally (mac) everything works perfectly. As of right now (using the syntax above) I am at least getting the default codeigniter 404 page. When use

error_log(__FILE__); 

at the top of each class, all I am getting to is My_Controller.php

Thank you for any suggestions!

Codeigniter change log says

Changed filenaming convention (class file names now must be Ucfirst and everything else in lowercase).

So you controllers and files name should be

• My_controller (only M upper case rest lower case)
• Public_controller
• Application_controller
• Foo_controller

I myself don't like new naming convention CI-2 was better in this case.

Note:

Controller name Public_Controller(C uppercase) and file name Public_controller.php may work but I prefer to keep both name same so controller name should be Public_controller.
