Even though it seems incredibly unlikely, isn't is safer to just not worry about it and use unique ids instead? Why take the risk when you can use an autonumber from a database or md5(uniqid(rand(), true)), or even: time() . md5(uniqid(rand(), true)) if you want to be really paranoid? -- Adam Bregenzer adam@bregenzer.net
