DERP.获取'致命错误:无法使用stdClass类型的对象作为数组'

我不知道我在这里做错了什么:

foreach ($json->result->items[$key]->attributes->attribute as $attrib => $val) 
{
    if($json->result->items[$key]->attributes->attribute[$attrib]->name == 'cannot_trade')
    {
        $notrade=1;
        echo 'Item ' . $key . ' is not tradeable' . $br;
    }
}

这是数据:

[attributes] => stdClass Object
(
  [attribute] => Array
  (
    [0] => stdClass Object
    (
      [name] => custom employee number
      [class] => set_employee_number
      [value] => 0
    )
    [1] => stdClass Object
    (
      [name] => cannot trade
      [class] => cannot_trade
      [value] => 1
    )
  )
)

本质上,我正在尝试测试'属性'数组是否具有cannot_trade东西.有时,父对象没有"属性"对象
