Generate random string

This PHP function will help you generate random strings of any length. Useful for your web applications like user registration, password resets or something similar. Don't use it for unique strings because it will not do that. It's possible (and most likely it will) to output strings that were generated before. Anyways, hope it helps someone.

Usage:

<?php
echo r_string(6);//Where 6 is the number of strings we need (length)
?>

<?php
function r_string($len) {
	list($usec, $sec) = explode(' ', microtime());
	$seed =  (float) $sec + ((float) $usec * 100000);
	srand($seed);
	$newstring = md5(rand());
	if ($len) {
		return substr($newstring,0,$len);
	} else {
		return $newstring;
	}
}
?>
