What does parent::Controller(); do?

[eluser]Ryuuzaki92[/eluser]
i was wondering what does

Code:

parent::Controller();

in

Code:

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();    
    }
    
    function index()
    {
        $this->load->view('welcome_message');
    }
}

do. i've seen other frameworks before and they don't require that function when constructing.

The answer you can find in php4 constructors

so i don't have to put it in php5?

No you have to use it because they haven't added a php5 __construct function. So in php4 and php5 you use the same methods so when you change from php4 to php5 ot the other way around your code keeps working.
