Or you could do something like is mentioned above. You don't have to add a column to the user table, you could make a new table and just use any random value as a id into the table (this is how activation and password changes work, using the useractivation table. Maybe you could figure out a way to use that same table).

Or maybe you just wanted to know the name of the php function? It's md5().
OK. Let's say that i want add MD5 with userid like


register.php?referrerid=1&invite=5808409b7ba1463c0d518dca3bb31d0e

See, If I want add the hash how can I ?
