        while (explode (":",$cart)){
                $cartitem = "item[".$numofitems ."]";
                $$cartitem = $cartarray[$numofitems];
                $numofitems++;
                echo $cartitem;
        }

}else{

        session_register("cart");
        }

ok - first of all we check to see if the cart exists....if it does we continue...if not we exit......then i take the variable ($cart) and split it apart at the ':'s. the problem that i run in to is that i can't get the loop to stop looping when there is nothing more to be split because it is at the end of $cart. is there a way to do this? do i make sense? ~kurth

Where's the loop? It's not quite clear what you're attempting to do here. Can you include the loop itself and explain a bit more exactly what effect you're going for? if (session_is_registered("cart")){

      $cartitem = "item[".$numofitems ."]"; //set cartitem to item[#]
      $cartarray = explode (":",$cart); //separate cart at the colons
      if ($cartarray){
              $$cartitem = $cartarray[$numofitems]; //make $$cartitem equal to item[#]

and then set that to cartarray[#]

              $numofitems++; //duh
              echo $cartitem;
      }elseif (!$cartarray){
      echo "done!";
      }

}else{

      session_register("cart");
      }
