как перевести?

$us_auth = mysql_query("SELECT * FROM `users` where `password` = '".$password."', `id` = '".$user_id."' LIMIT 1");
$user = mysql_fetch_assoc($us_auth);

$sql_us = "SELECT * FROM `users` where `id` = '1' LIMIT 1";
$us_sql_start = mysqli_query($sql_us);
$user = mysqli_fetch_assoc($us_sql_start);

echo ''.$user['login'].'';

не работает

$us_auth = $mysqli->query("SELECT * FROM `users` where `id` = '".$user_id."', `password` = '".$password."'");
$user = $us_auth->fetch_assoc();

разобрался!
