This is one I like to use jozef.
function generate_password($length = 10) {
$allowable_characters = "abcdefghjkmnopqrstuvwxyz23456789";
$ps_len = strlen($allowable_characters);
mt_srand((double)microtime()*1000000);
$pass = "";
for($i = 0; $i < $length; $i++) {
$pass .= $allowable_characters[mt_rand(0,$ps_len-1)];
}
return $pass;
}
Its been working well for me for sometime.

Subject: Random Password problem
I am using this php in order to create, store and send random passwords
to people who want to join my mailing list.
<?php
function random_password () {
$seed = (integer) md5(microtime());
mt_srand($seed);
$password = mt_rand(1,99999999);
$password = substr(md5($password), 3,9);
return $password;
}
?>
<?php
$msg = random_password();
echo $msg;
?>
I seem to be getting the same number very often which makes me fear that
this is not so random. I am a noob so I do not know if this is
coincidence or a fault in my coding.
Right now, I have been setting up passwords manually, but would like
users to be as free from me as possible. Any direction would be helpful.
BTW, I keep getting the following number an absurd amount of times. I
have deleted cookies and even gone to other machines, and yet it still
generates this number.
