Php 找出多维数组中的差异

我想找到以下数组的不同类型

第一个阵列：

Array
(
[0] => Array
    (
        [MONTH] => 1
        [year] => 2014
        [Total_days] => 2
    )

[1] => Array
    (
        [MONTH] => 2
        [year] => 2014
        [Total_days] => 2
    )

[2] => Array
    (
        [MONTH] => 3
        [year] => 2014
        [Total_days] => 2
    )

[3] => Array
    (
        [MONTH] => 4
        [year] => 2014
        [Total_days] => 2
    )

[4] => Array
    (
        [MONTH] => 6
        [year] => 2014
        [Total_days] => 1
    )

[5] => Array
    (
        [MONTH] => 1
        [year] => 2015
        [Total_days] => 1
    ))

第二个阵列：

Array
(
[0] => Array
    (
        [MONTH] => 1
        [year] => 2014
        [total] => 4
    )

[1] => Array
    (
        [MONTH] => 2
        [year] => 2014
        [total] => 6
    )

[2] => Array
    (
        [MONTH] => 3
        [year] => 2014
        [total] => 5
    )

[3] => Array
    (
        [MONTH] => 4
        [year] => 2014
        [total] => 6
    )

[4] => Array
    (
        [MONTH] => 5
        [year] => 2014
        [total] => 2
    )

[5] => Array
    (
        [MONTH] => 6
        [year] => 2014
        [total] => 2
    )

[6] => Array
    (
        [MONTH] => 7
        [year] => 2014
        [total] => 2
    )

[7] => Array
    (
        [MONTH] => 8
        [year] => 2014
        [total] => 1
    )

[8] => Array
    (
        [MONTH] => 9
        [year] => 2014
        [total] => 1
    )

[9] => Array
    (
        [MONTH] => 10
        [year] => 2014
        [total] => 2
    ))

现在，如何找到同一年和同一个月的array2和array1之间的总差异

例如，在array2中有array[6]=>array ( [月份]=>7 [年份]=>2014年 [总数]=>2 )

---

在数组中，1在索引数组中具有相同的年份和月份[4]。这里如何找到2-1=1的总差异？

尝试使用

array\u diff

方法在

array

中找到差异。首先添加年、月和日期……然后使用date\u diff（）找到差异。

您认为如何找到差异？首先，使用键名遍历数组以匹配这两个变量。自己做点努力。我们不是你的自由劳工。
