Question

我想找到下面数组的不同。

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
    ))

现在如何在同一年和同一个月找到array2到array1之间的总差异？

例如，在array2中有array [6] =＆gt;排列（ [MONTH] =＆gt; 7 [year] =＆gt; 2014 [total] =＆gt; 2 ）

在array1中，索引数组[4]中的年份和月份相同。这里如何找到总差异为2-1 = 1？

Answer 1

尝试使用array_diff方法查找array中的差异。

Answer 2

首先附加年，月和日....然后使用date_diff（）

找到差异

找出多维数组的差异
