   printf("Connect failed: %s\n", mysqli_connect_error());
   exit();
}

$query  = "SELECT CURRENT_USER();";
$query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5";

/* execute multi query */
if (mysqli_multi_query($link, $query)) {
   do {
       /* store first result set */
       if ($result = mysqli_store_result($link)) {
           while ($row = mysqli_fetch_row($result)) {
               printf("%s\n", $row[0]);
           }
           mysqli_free_result($result);
       }
       /* print divider */
       if (mysqli_more_results($link)) {
           printf("-----------------\n");
