Random Number 11-99 w/o Any '0's ?

[austingecko]

I want to create a random number not containing an '0' Why? A user may easily confuse a 0 (numerical) with an O (letter).

mt_rand (11, 99) gets a random number between 11 and 99, but that includes 20, 30, 40, 50, 60, 70, 80, and 90.

I'm not sure how to proceed. Any suggestions?

Thanks.

here are a couple of ideas...

mt_srand ((double) microtime() * 1000000);
$num = mt_rand (11, 99);
while (ereg("0",$num)) {
mt_srand ((double) microtime() * 1000000);
$num = mt_rand (11, 99);
}

or...

mt_srand ((double) microtime() * 1000000);
$num = mt_rand (11, 99);
if (ereg("0",$num)) {
mt_srand ((double) microtime() * 1000000);
$ones = mt_rand (1, 9);
$num = str_replace("0",$ones,$num);
}

or simply...

mt_srand ((double) microtime() * 1000000);
$num = mt_rand(1,9) . mt_rand(1,9);

mt_rand(1,9) . mt_rand(1,9);

Ah, of course. Thanks!
