Is Controller Index are not recommended?

[eluser]rahendz[/eluser]
I create controller like structure below :

Code:

controller
- app
-- index.php

and inside index.php i put controller class like below :

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Index extends CI_Controller {
public function index()
{
  echo "Here i am";
}
}
/* End of file index.php */
/* Location: ./application/controllers/zudan/index.php */

and i accessed using this url like below :

Code:

http://localhost/index.php/app/index

and it show that echoing twice like below :

Code:

Here i amHere i am

so what i'm gonna ask is Controller Class with Index as a Name of Class not recommended since it called twice? or i got something wrong? thanks before and sorry for my bad english.

That's a PHP limitation, or more specifically a BC feature for the PHP4 days. Having a method name that matches the class name makes it a constructor.
