Code:

class Item extends Controller {
    function Item()
    {
        parent::Controller();
    }
    function abc(){
        echo $a;
    }
}

when visit http://www.*.com/item/abc display the following errors,How to hide that.

By defining your variable $a before you use it.

What are you expecting to get? And why? You must be doing something, somewhere with $a... right?
