$cart is an object. Its method generate_cart_id() returns some value,
which is assigned to both the variable $cartID and the object property
$cart->cartID.

A more complex way to code this would be:

$result = $cart->generate_cart_id();
$cart->cartID = $result;
$cartID = $result;

What's ugly about this is that the same value is stored in an object
property and in a variable. Without knowing the context this doesn't
look good.
