php mysql procedure实现获取多个结果集的方法【基于thinkPHP】

protected function getRs($id) {
    $db = new mysqli(C("DB_HOST"), C("DB_USER"), C("DB_PWD"), C("DB_NAME"), C("DB_PORT"));
    if (mysqli_connect_errno())
      throw_exception(mysqli_connect_error());
    $sql = "call `room_match`.`wsKocMatchLoadResultHeader`($id);";
    $results = array();
    if ($db->multi_query($sql)) {
      do {
        $records = array();
        if ($result = $db->use_result()) {
          while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
            $records[] = $row;
          }
          $result->close();
        }
        $results[] = $records;
      } while ($db->next_result());
    }
    $db->close();
    $this->assign("list1", $results[1]);
    $this->assign("list2", $results[2]);
    $this->assign("list3", $results[3]);
}
