PHP，合并在多维数组的键 [英] PHP, Merge keys in multidimensional array

问题描述

如果我有一个数组，它看起来是这样的：

If I have an array which looks something like this:

Array
(
    [0] => Array
    (
        [DATA] => Array
    (
        VALUE1 = 1
        VALUE2 = 2
    )
    )
    [1] => Array
    (   
        [DATA] => Array
    (
        VALUE3 = 3
        VALUE4 = 4
    )
    )
)

和希望把它变成这样：

Array
(
    [0] => Array
    (
        [DATA] => Array
    (
        VALUE1 = 1
        VALUE2 = 2
        VALUE3 = 3
        VALUE4 = 4
    )
    )
)

我基本上要合并所有相同的按键，在同一水平。
什么是实现这一目标的最佳途径？
请问array_merge功能有什么用处？

I basically want to merge all the identical keys which are at the same level. What would be the best route to accomplish this? Could the array_merge functions be of any use?

我希望这是任何形式的意识，在此先感谢所有帮助我能。

I Hope this makes any sort of sense and thanks in advance for any help i can get.

推荐答案

您可以使用<一个href=\"http://php.net/manual/en/function.array-merge-recursive.php\"><$c$c>array_merge_recursive合并所有项目的原始数组在了一起。而且，由于该函数采用可变数量的参数，使得它笨拙的时候这个数字是在编译时未知的，你可以使用<一个href=\"http://php.net/manual/en/function.call-user-func-array.php\"><$c$c>call_user_func_array为了更加方便：

You can use array_merge_recursive to merge all the items in your original array together. And since that function takes a variable number of arguments, making it unwieldy when this number is unknown at compile time, you can use call_user_func_array for extra convenience:

$result = call_user_func_array('array_merge_recursive', $array);

结果将具有顶层的您的输入修剪掉（逻辑，因为你正在合并多个项目到一个），但将保留所有剩余的结构。

The result will have the "top level" of your input pruned off (logical, since you are merging multiple items into one) but will keep all of the remaining structure.
