PHP组织具有相同值的行

我正在从sql server检索数据，然后以有组织的方式呈现这些数据。
我有这样一个对象数组：

Array
(
[0] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => edit
        [http_method] => post
    )

[1] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => edit
        [http_method] => get
    )

[2] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => create
        [http_method] => post
    )

[3] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => create
        [http_method] => get
    )
)

Array(
    [0] => Array(
        [controller] => controller1,
        [controller_methods] => Array (
            [0] => Array (
                [controller_method] => create,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            ),
            [0] => Array (
                [controller_method] => edit,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            )
        )
    ),
    [0] => Array(
        [controller] => controller2,
        [controller_methods] => Array (
            [0] => Array (
                [controller_method] => create,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            ),
            [0] => Array (
                [controller_method] => edit,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            )
        )
    )
)

不知何故，我需要转换成这样：

Array
(
[0] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => edit
        [http_method] => post
    )

[1] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => edit
        [http_method] => get
    )

[2] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => create
        [http_method] => post
    )

[3] => stdClass Object
    (
        [post_id] => 1
        [controller] => Cato
        [controller_method] => create
        [http_method] => get
    )
)

Array(
    [0] => Array(
        [controller] => controller1,
        [controller_methods] => Array (
            [0] => Array (
                [controller_method] => create,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            ),
            [0] => Array (
                [controller_method] => edit,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            )
        )
    ),
    [0] => Array(
        [controller] => controller2,
        [controller_methods] => Array (
            [0] => Array (
                [controller_method] => create,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            ),
            [0] => Array (
                [controller_method] => edit,
                [http_methods] => Array (
                    [0] => get,
                    [1] => post
                )
            )
        )
    )
)

在使用sql db处理php时，我总是遇到类似的情况

有什么方便的方法吗？

结果数据中的

controller1

和

controller2

来自哪里？它们不会出现在输入中的任何位置。另外，除了这个

控制器

键外，两个输出数组似乎是相同的，从一种格式到另一种格式的逻辑是什么？我只是举一个例子，实际上控制器列是不同的。每个控制器都有许多控制器方法。每个控制器方法都有许多http\U方法。我需要组织它们。所以输入数据实际上只代表一个控制器？
