php执行多个存储过程的方法【基于thinkPHP】

$this -> queryID -> close();

public function query($str) {
    $this -> initConnect(false);
    if (!$this -> _linkID) {
      return false;
    }
    $this -> queryStr = $str;
    //释放前次的查询结果
    if ($this -> queryID)
      $this -> free();
    N('db_query', 1);
    // 记录开始执行时间
    G('queryStartTime');
    $this -> queryID = $this -> _linkID -> query($str);
    // 对存储过程改进
    $ret = array();
    $this -> debug();
    if (false === $this -> queryID) {
      $this -> error();
      return false;
    } else {
      $this -> numRows = $this -> queryID -> num_rows;
      $this -> numCols = $this -> queryID -> field_count;
      $ret = $this -> getAll();
    }
    //主要将这段移动了一下，关闭结果集
    if ($this -> _linkID -> more_results()) {
      while (($res = $this -> _linkID -> next_result()) != NULL) {
        $this -> queryID -> close();
      }
    }
    return $ret ;
}

$db = new mysqli(C("DB_HOST"), C("DB_USER"), C("DB_PWD"), C("DB_NAME"));
if (mysqli_connect_errno())
throw_exception(mysqli_connect_error());
$t2 = microtime(true);
echo "数据库连接用时：" . (($t2 - $t1)) . "s 
";
$arr = array();
// 1st Query
$procedure = "call p1()";
$result = $db->query($procedure);
if ($result) {
// Cycle through results
while ($row = $result->fetch_object()) {
//添加到对象数组
$arr[] = $row;
}
// 这里是最重要的，需要将游标移动下一个结果集
$result->close();
$db->next_result();
}
$procedure = "call p2()";
$result = $db->query($procedure);
if ($result) {
// Cycle through results
