I don't understand php, but in java you could simply remove the object from a Map
With a key value.

Map <CartItem,Integer>item = new HashMap();

*Simply use ur hand to remove it and return it to d store shelf!
If ur in a supermarket/mart.

If online use the "remove/delete/save for l8r" button
*

pardon the sakazm but ur question is ripe for misinterpretation.

True, PHP does the same. @op, just use var_dump($_POST); to get the structure of the array - you can then post it here so we tell you how to remove it - i might not be here, i am hardly here these days. Been building my www.Nairaland.com - and that is taking like all my time.
