   $password = "";
   $dbname = "TUTORIALS";
   $conn = new mysqli($servername, $username, $password, $dbname);
   
   if (!$conn->real_connect($servername, $username, $password, $dbname)) {
      die('Connect Error (' . mysqli_connect_errno() . ') '. mysqli_connect_error());
   }
   echo "Database connected";

   $query  = "SELECT CURRENT_USER();";
   $query .= "SELECT name FROM tutorials_auto ORDER BY ID";

   if ($conn->multi_query($query)) {
      do {
         if ($result = $conn->use_result()) {
            while ($row = $result->fetch_row()) {
               printf("%s\n", $row[0]);
            }
            $result->close();
         }
         if ($conn->more_results()) {
            printf("******************\n");
         }
      } while ($conn->next_result());
   }

   mysqli_close($conn);
?>
