    You will need to use

     $result = $mysqli->query("SELECT 1 FROM `users` WHERE `k1`='$string1' AND 'k2'='$$string2'");
    if ($result = $mysqli->query("SELECT 1 FROM `users` WHERE `k1`='$string1' AND 'k2'='$$string2'"))
        {

        if($result->num_rows==0)
        {
        printf("Sorry");
        }
        }

    As you are making query as SELECT statement.
