php循环遍历stdClass对象和数组

Question

您好，我使用 woocommerce rest API 访问 woocommerce 网站上的订单信息。

数据以 json 格式返回，我可以通过这个循环访问所有数据：

$orders = $connect->orders->get();
        $order_numbers = $orders->orders;

        foreach ($order_numbers as $order_number) {            

            $order_data = $connect->orders->get($order_number->order_number);

            echo '</br>' . $order_number->order_number . '</br>';
            echo $order_data->order->total . '</br>';

            $line_items = $order_data->order->line_items;

            foreach($line_items as $item){
                echo $item->name . ' x ' . $item->quantity . '</br>';   
            }

        }

第一行是获取订单列表的 API 调用。

这允许我在不指定 order_number 的情况下从第一个对象输出数据。但是，当访问 stdObject 中的数组时，例如“line_items”，我必须定义一个订单号。为了克服这个问题，我这次在 foreach 内部进行了另一个 api 调用，指定了访问信息的订单号。

$order_data = $connect->orders->get($order_number->order_number);

问题在于第二个 API 调用大大减慢了整个页面的速度。

有没有办法让我将其减少为单个 api 调用以加快页面渲染速度。

作为参考，这是我正在访问的数据：

    object(stdClass)[16]
      public 'id' => int 22
      public 'order_number' => int 22

根据他们的规范 (http://woothemes.github.io/woocommerce-rest-api-docs/#view-list-of-orders)，您应该已经拥有 $orders 结果中的所有信息。
