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]);}
