php vars & classes

[copernic67]

Can U explain me why in the following file, the last call to the fonction $cart->printle(); doesnt print anything?

Why doesn't the class panier keep all the items added to the panier in the var $item ?

Thanks,

lejoe

<?php

class Panier {

var $items;

function add_item ($artnr, $num) {
$this->items[$artnr] += $num;
}

function printle () {
print_r($items);
}

}

$cart = new Panier;

$cart->add_item("0", 0);
$cart->add_item("1", 1);
$cart->add_item("2", 2);

$cart->printle();

?>

it needs to be print_r($this->items);
