Generate cryptographically secure random numbers in php

Question

PHP\'s rand() function doesn\'t give good random numbers. So I started to use mt_rand() which is said to give better results. But how good are thes

Answer 1

There is no such thing as a "perfect" random number. No matter what subjective definition of "perfect" you have. You can only achieve pseudo-random.

I was simply trying to point you in the right direction. You asked a question about perfect random numbers, even if perfect was in quotes. And yes, you can improve randomness. You can even implement heuristic or "natural" algorithms, such ideas like "atmospheric noise" -- but still, you're not perfect, not by any means.
