Re: Shopping Carts

I use sessions combinded with utc function mtime() { $mtime = microtime(); $mtime = ereg_replace('\.', '', $mtime); $mtime = explode(' ', $mtime); $mtime = $mtime[1] . $mtime[0]; return($mtime); } will ALLWAYS return a unique number, store this number in a session, each user gets assigned a sessionID now each user has their own number, 100% unique to themselves. this is how I seperate my users. Ive built quite a few cart systems with this aproch. I store the cart right in the sessions, but I have also set systems up where the cart is right in the db. I did the later because a client wanted to have a way to see the % of users that put things in their cart and never purchased, and % of products purchased to % abandonded in their cart. Your right on the IP system, here in the office I share the same IP with 12 people throught a NAT. I dont know if you need to use an IP at all, if this is just for a cart... then big deal, some script kiddy could try 36^32 possible combinations of a PHPSESSID to try and hijack their cart ! haha. maybe for a something a little more secure.
