推荐答案

类似这样的事情:

$object->_items[index]->_productId

但是，如果_items是私有的，那么您将需要一个公共获取器或将Reflection类弄乱.您可以将私有属性设置为可通过ReflectionProperty访问 试试这个:

But if _items is private you will need a public getter or mess with the Reflection classes. You can set the the private property to be accessible through ReflectionProperty Try this:

    $reflectionObject = new ReflectionObject($yourObject);
    $property = $reflectionObject->getProperty('_items');
    $property->setAccessible(true);
    $items = $property->getValue($yourObject);
