{
$chars=’ABDEFGHJKLMNPQRSTVWXYabdefghijkmnpqrstvwxy23456789#%*’;
// characters to build the password from
mt_srand((double)microtime()*1000000*getmypid());
// seed the random number generater (must be done)
$password=”;
while(strlen($password)<$len)
$password.=substr($chars,(mt_rand()%strlen($chars)),1);
return $password;
}

Sample 2:

{
$password_len = 7;
$password = ”;
