Naming convention issues when using codeigniter in windows and linux

Question

I have made a web application in codeigniter framework. I was developing the app on a Windows machine and the final version runs perfectly well on the same (ie windows, wamp to be precise ). Now i need to deploy the app on a ubuntu server. After the initial login required in the app, it does not display any other page.On inspecting the console, I found this

[09:08:37.255] GET http://localhost/sac.org/index.php/member [HTTP/1.0 500 Internal Server Error 17ms]

I think this is a very common problem, as is evident from these questions:

codeigniter framework not working on linux

Windows code not working on linux

codeigniter upload not working on linux

and here too Codeigniter issue

and many more. The answers mentioned in these threads are not working for me. Is there some way to solve this issue?

My code sample is

    }
    private function accesscheck(){

Answer 1

As advised by Prix, I checked my error log and found that the problem was due to syntax error. I was using Function array dereferencing which has been added in PHP 5.4.0 but my server was running PHP 5.2.

The solution is here

The solution worked. I had to resort to this method rather than upgrading my PHP version because the server is running UBUNTU 12.04 which has no repos for PHP 5.4 .
