关于php减少数组维度的问题 求大神支招

Array
(
[jwc_grades] => Array
(
[0] => Array
(
[2012] => Array
(
[1] => Array
(
[term_point] => 3.5
[term_average] => 88
[grades] => Array
(
[0] => Array
(
[jwc_grade_id] => 5
[course] => 阿什顿
[point] => 2
[grade] => 1
)

                                    )                            )                    )            )        [1] => Array            (                [2012] => Array                    (                        [1] => Array                            (                                [term_point] => 3.5                                [term_average] => 88                                [grades] => Array                                    (                                        [0] => Array                                            (                                                [jwc_grade_id] => 6                                                [course] => 是电风扇等                                                [point] => 2                                                [grade] => 1                                            )                                    )                            )                    )            )        [2] => Array            (                [2012] => Array                    (                        [2] => Array                            (                                [term_point] => 3.5                                [term_average] => 88                                [grades] => Array                                    (                                        [0] => Array                                            (                                                [jwc_grade_id] => 7                                                [course] => 不错                                                [point] => 2                                                [grade] => 1                                            )                                    )                            )                    )            )

)

如何让它变成
Array
(
[jwc_grades] => Array
(

                [2012] => Array                    (                        [1] => Array                            (                                [term_point] => 3.5                                [term_average] => 88                                [grades] => Array                                    (                                        [0] => Array                                            (                                                [jwc_grade_id] => 5                                                [course] => 阿什顿                                                [point] => 2                                                [grade] => 1                                            )                                    )                            )                    )                [2012] => Array                    (                        [1] => Array                            (                                [term_point] => 3.5                                [term_average] => 88                                [grades] => Array                                    (                                        [0] => Array                                            (                                                [jwc_grade_id] => 6                                                [course] => 是电风扇等                                                [point] => 2                                                [grade] => 1                                            )                                    )                            )                    )                 [2012] => Array                    (                        [2] => Array                            (                                [term_point] => 3.5                                [term_average] => 88                                [grades] => Array                                    (                                        [0] => Array                                            (                                                [jwc_grade_id] => 7                                                [course] => 不错                                                [point] => 2                                                [grade] => 1                                            )                                    )                            )                    )

就是让它的第三维消失 减少一维

解决方案

我的第一反应是，你的这个需求其实就很奇怪。让第三维直接消失。
我不太知道你的具体的问题是什么，为什么会有这么奇怪的想要实现的功能。
但是还是比较建议，稍微看看自己的设计是不是可以有改进的地方，很多时候，如果一个东西很丑陋，那说明还不是最佳的答案。

解决方案二：
你的需求是什麼呢？

你的數組有問題，多個2012的key放同一個數組裡面是不可能的。
