I have a shopping cart type system set up which keeps track of the cart contents using a SESSION variable, where $_SESSION['cart'][$item_id'] is equal to the quantity, so the name/value pair is all the information I need. But sessions are unreliable on the free server I am currently using for this website (not my choice), so I had start using cookies because users were being sporadically logged out, sometimes just on a page refresh. I want to find a way to set a cookie to remember the cart items as well, and I thought setting a cookie for each item/quantity pair was the way to go until I started trying to figure out how to unset all those cookies if the user empties their cart. Is there any way to set cookies with an array for the name? Intead of $_COOKIE['item_number'] have $_COOKIE['cart']['item_number'] like I have the SESSION?
