[PHP] Re: md arrays

[Niklas Lampén]

I suggest you to use something like this as your cart:
  $cart => Array
    (
      [LT4697] => Array
        (
          [qty] => 1
        )
      [LT1234] => Array
        (
          [qty] => 2
        )
    )
So you can easily check with in_array() / is_array() if product is in 
the cart allready.

                (
                    [id] => LT4153
                    [qty] => 3
                )
            [2] => Array
                (
                    [id] => LT4697
                    [qty] => 1
                )
            )
I'm aware that I probably could just have a single dimension array, but 
there's more to be added later, and I prefer to treat this data like 
rows from mysql.

Anyway, what's the *least expensive* way to:
- check if an item (eg LT4153) is in the cart already?
- get the current qty of an item (eg LT4153)
The cart won't be big, so a foreach() on the cart isn't out of question, 
but I'd like to know the *right* way :)
