Question

我正在使用

      foreach ($content as $item) {

迭代购物车的一些商品。我需要从每个项目中获取'type'的值。每个$ item都有一个如下所示的数组：

  'item' => 
    object(stdClass)[6]
      public 'cart_item_id' => string '304' (length=3)

如何在'node'中获取'type'的值？我想将它设置在'item'中。我试过了：

      $node->type;
      $node['type'];
      $item['node']->type;

Answer 1

从您的错误消息Cannot use object of type stdClass as array 我猜$ item不是数组而是stdClass。

请尝试：$item->node->type。

Answer 2

$node = $item['node'];
$item['item']->type = $node->type;

在数组PHP中访问变量内部对象
