Using numbers only in Lost Password

[pattycake]

I found the code... it does in fact allow numbers and, it excludes the letters o and O (cap o)

I'd like to remove the zero too but I'm not a good enuff php programer to do so

Here is the code that generates the password.

function fetch_random_password($length = 8)
{
	$password_characters = 'ABCDEFGHJKLMNPQRSTUVWXYZabcdefghjkmnpqrstuvwxyz';
	$total_password_characters = strlen($password_characters) - 1;

	$digit = vbrand(0, $length - 1);

	$newpassword = '';
	for ($i = 0; $i < $length; $i++)
	{
		if ($i == $digit)
		{
			$newpassword .= chr(vbrand(48, 57));
			continue;
		}

		$newpassword .= $password_characters{vbrand(0, $total_password_characters)};
	}

	return $newpassword;
}

/**

*/
function fetch_random_string($length = 32)
{
	$hash = sha1(TIMENOW . SESSION_HOST . microtime() . uniqid(mt_rand(), true) . implode('', @fstat(fopen( __FILE__, 'r'))));

	return substr($hash, 0, $length);
}

*/
function vbrand($min = 0, $max = 0, $seed = -1)
{
	mt_srand(crc32(microtime()));

	if ($max AND $max <= mt_getrandmax())
	{
		$number = mt_rand($min, $max);
	}
	else
	{
		$number = mt_rand();
	}
	// reseed so any calls outside this function don't get the second number
	mt_srand();

	return $number;
}
