How can I write a script that will generate a random unique link on submit in PHP?

Currently when a user clicks a button, a on submit URL is generated in numbers. E.g.: http://rcpaste.com/20/.

But I would like to generate a random alphanumerical code instead of purely a numerical one, how can I do this?

Why does it need to be random? Why not just make a simple count up with alphanumeric in it? – Oliver Nybroe Dec 27 '15 at 12:21
A random string can not be guaranteed to be unique. That is a contradiction. – arkascha Dec 27 '15 at 12:22
