    while ($i < $length) {
    // pick a random character from the possible ones
    $char = substr($possible, mt_rand(0, strlen($possible)-1), 1);

    // we don’t want this character if it’s already in the password

Keep this function at the bottom of your PHP script, or in some other dedicated .php file for this function and include that PHP script in your present script.

Then use this function like

$new_password = generatePassword (10); //whatever length
$sql = mysql_query("INSERT INTO ..... .... (`password`, ... ... ...) VALUES ($new_password, ... ... ...)")

You could just use one of the built in random functions or hash functions.
