I have an array that looks something like this:
$cart => Array
(
[0] => Array
(
[id] => LT4697
[qty] => 1
) [1] => Array
(
[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 :)
TIA Justin
