[PHP] Classes and arrays

[Stefan Kostopoulos]

Hi!

Can anybody explain to me why this script outputs:

oneone

instead of:

zeroone

???????????

Thanks,

stefan


<?
class Cart {
    var $items;  // Items in our shopping cart
   
    function add_item ($id,$text) {
        $this->$items[$id] = $text;
    }
   
   function output($id){
                
                echo $this->$items[$id];
         }

}


$c = new Cart;
$c->add_item(0,"zero");
$c->add_item(1,"one");
$c->output(0);
$c->output(1);


?>
