我想从
[range]=stdClass对象中获取id,正如您可能看到的,您的产品
对象有一个属性range\u id
:
Product Object

[name] => Simon Test Cup
[code] => 123456789
[category_id] => 3
[range_id] => 26 // <--- here!
[price] => 10.00
...
但是可能,Product
和Range
类定义了允许您访问这些信息的方法,您应该使用它们。您只需阅读文档,了解如何使用它们
$product->_related["_related"]["range"]->key
但是我不确定我是否理解得很好,你可以说$object->_-related[“_-related”][“range”],但是这个结构大概是一个对象的结构,它有访问器,可以访问你可能想要的东西。你显然不想担心事物的内部结构 假设Felix的答案不起作用(这可能很好),我猜\u相关的
字段是受保护的。在这种情况下,该类中应该有一个访问器方法,以便获取相关对象。请在对象上使用get\u class\u methods()
,并使用可用的方法编辑文章
$product->_related["_related"]["range"]->key
