There is a simply class:
class Shop {
var $cart;
function Shop(&$shop_cart) {
$this->cart = $shop_cart; # there is problem
}
}
and variable $shop using "cart_main" session variable:
$shop = new Shop ($_SESSION["cart_main"]);
Session variable has been initialized. Unfortunatelly it doesn't work, when I use
$this->cart = $shop_cart; Everytime when I try to use $this->cart->any_variable there is no
previous data. When I change to this:
class Shop {
var $cart;
function Shop(&$shop_cart) {
$this->cart = &$shop_cart; # reference
}
}
everything is ok. Why? Passing variable by reference (in Shop function) should solve everything. But
it doesn't.
