From a cryptographic point of view this is terrible.
First letter is always capital, only symbols 0-9 a-f are used...

return substr(base64(mt_rand()),0,$length);
is faster shorter and will do a better job.

base64 is not a native php function

You probably meant:

base64_encode(mt_rand()),0,$length);
