hrm... varaible varaibles and looping

look at this i have $cart with "fields" separated by ':'. i explode the variable...however..i can't get it to loop and add one to the variable that points to the array...i can't figure out how to lloop until the end of the array is reached.....any ideas? look at the code. 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"); } ~kurth Kurth Bemis - Network/Systems Administrator, USAExpress.net/Ozone Computer There is no sin except stupidity. -- Oscar Wilde kurth@usaexpress.net | http://www.usaexpress.net/kurth PGP key available - http://www.usaexpress.net/kurth/pgp Fight Weak Encryption!
