php - PHP访问解码的JSON

我有一个PHP脚本，该脚本使用以下命令将JSON字符串成功解码为PHP对象：

$decodedJSON = json_decode($responseString);

当$decodedJSON打印到响应时，我得到：

stdClass Object
(
    [response] => stdClass Object
        (
            [total_rows] => 2379
            [data] => Array

                            [17] => 1
                        )

                )

            [fields] => Array
                (
                    [0] => subject_key
                    [1] => factual_id
                    [2] => name
                    [3] => address
                    [4] => address_extended
                    [5] => po_box
                    [6] => locality
                    [7] => region
                    [8] => country
                    [9] => postcode
                    [10] => tel
                    [11] => fax
                    [12] => category
                    [13] => website
                    [14] => email
                    [15] => latitude
                    [16] => longitude
                    [17] => status
                )

            [rows] => 10
            [cache-state] => CACHED
            [big-data] => 1
            [subject_columns] => Array
                (
                    [0] => 1
                )

        )

    [version] => 2
    [status] => ok
)

我的问题是：如何访问“字段”数据？我试过使用$decodedJSON["fields"]以及$decodedJSON[0]["fields"]和$decodedJSON[0][2]以及许多其他变体。

有人看到我在做什么错吗？

非常感谢，

尝试使用$decodedJSON->response->fields
