PHP Generate random password Using PHP

Generate random password Using PHP

Hi,
I want to know how to generate random password in PHP. One of the ways of achieving this is to write a function for the same. I know that there are many methods of doing this. Can someone provide some other methods of doing that?

Regards,
Fred

<?
function Random_Password($length) {
srand(date("s"));
$possible_charactors = "abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ";
$string = "";
while(strlen($string)<$length) {
$string .= substr($possible_charactors, rand()%(strlen($possible_charactors))),1);
}
return($string);
}
echo Random_Password(8);

Re: Generate random password Using PHP

or simply use this

$pass = md5(uniqid(rand(), true));
