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.
