[PHP] Adding to cart function.

2002-10-25 Thread Steve Jackson 
My boss wants me to add a number of items to the cart based on a user
form input. At the moment my add to cart function  checks if anything is
in it and then increments one item (using this code). I can supply the
full function if required but just this part would get me away I think.

if($cart[$new])
  $cart[$new]++;

Instead of incrementing by one how do I increment by a variable which
would be the form input?
