Как записать код иначе?

$cookies = md5(rand(0, 255));
$db = mysql_connect("HOST", "LOGIN", "PASSWORD");
mysql_select_db("SELECTED_DB", $db);
$user_login = $_POST['login'];
$user_password = $_POST['password'];
$password_selecting = mysql_query("SELECT password FROM users WHERE login='$user_login'");
$password_in_db = mysql_fetch_array($password_selecting);
if ($user_password == $password_in_db[0]){
setcookie('Authorization', $cookies);
$cookies_insert = ("INSERT INTO users (cookie) VALUES ('$cookies')");
}

$password = $_POST['password'];
$new_cookie = 'administrator_access';
if ($password == 'PASSWORD'){
$call_forwarding_true = header("Location:steam_costs.php");
setcookie('Authorization', $new_cookie);
}

$cookies_insert = ("INSERT INTO `users` (cookie) VALUES ('$cookies')");
