[PHP] On Random password

My new code is faster, a simple benchmark test:

Meir:

<?php

function random_password($length = 6)
{
	$characters = implode('', array_merge(range('a', 'z'), range('A', 'Z'), range(0, 9)));
	$characters = str_repeat(str_shuffle($characters), $length > 62 ? ceil($length/62) : 1);
	return substr($characters, 0, $length);
}

$start = array_sum(explode(' ', microtime()));

for ($i = 0; $i < 10000; $i++) {
	random_password(100);
}

$end   = array_sum(explode(' ', microtime()));
$final = $end - $start;

echo number_format($final, 4, '.', '').' seconds'; // 0.5664 seconds

?>

<?php

function random_password($length = 6)
{
	while (strlen($key) < $length) $key .= rand(0,1) ? chr(rand(48, 57)) : chr(rand(97, 122));
	return $key;
}

$start = array_sum(explode(' ', microtime()));

for ($i = 0; $i < 10000; $i++) {
	random_password(100);
}

$end   = array_sum(explode(' ', microtime()));
$final = $end - $start;

echo number_format($final, 4, '.', '').' seconds'; // 3.3504 seconds
