我在访问嵌套在数组中的 stdClass 对象的值时遇到一些困难。 问题是嵌套数组值不一致，我想知道是否有办法使用某种通配符或解析路径来访问它？这是数组的输出。

我试图获得的值是 [nid]，它在这里找到......
[products] => Array
(
[259] => stdClass Object
(
[order_product_id] => 259
[order_id] => 251
**[nid] => 71**
[title] => attributesw
[model] => uuuu
[qty] => 1
[cost] => 0.00000
[price] => 50.00000
[weight] => 0
[weight_units] => lb
问题是嵌套数组的值（在本例中为 [259]）总是在变化，我想知道是否有办法在不知道它所在的数组的值的情况下获取 [nid] 的嵌套值。 例如通配符。对不起，如果我的术语不合适，这不是我的专长，希望对您有意义。 非常感谢您的任何帮助！
我想通了....在阅读了我自己的问题后，我意识到我可以解析数组中的键，然后使用该键来获取值。
