PHP random unique identifier

In the construction of our booking system client can view their bookings online. At the moment the URL o开发者_如何学运维f their page is created as a sequential number. So /booking1, /booking2, /booking3 etc...

I'd rather have unique name a bit like the JSFiddle way of doing it. A series of letters and numbers.

Is that possible?

Would uniqid be good enough for what you need?

uniqid function seems to be what you are looking for.

you can use uniqid("bookingr", false);
