Randomizer url, how to implement by example?

Question

PHP

good time.
you need to make sure that there is a permanent unchanged url, for example:
site.ru / url
, when accessing which it scooped information from the file where the list of urls was, and gave each visitor a unique and list

, while each url issued by them was used only 1 time

tell me Perhaps there is something ready or how to implement something similar?
