The example from "relsqui at armory dot com" is wrong. It talks about bit operations and uses "&", but is actually an example of using modulus and should use "%". The idea is that "rand()%(x+1)" is faster than "rand(0,x)". I agree, it is. But not a lot.

Here's the fastest function I can think of for making pseudo-unique, valid IDs for HTML tags, in which the first character can't be a number:

function makeID() {
$s="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
return $s{rand()%52}.$s{rand()%62}.(repeat ad libitum).$s{rand()%62};
}
