将二维数组转换成一维PHP

问题描述

我有一个包含3阵列，非常类似内容的数组（下面的示例）。我在想，如果有把一切都成一个阵列，而不是3个独立的人一个简单的方法。一切我尝试似乎只是简单地覆盖数据，我留下了只从第3阵列的信息。

I have an array (sample below) containing 3 arrays with very similar content. I was wondering if there was an easy way to put everything into one array, rather than 3 separate ones. Everything I try seems to just overwrite the data and I'm left with the info from the 3rd array only.

array
  0 =>
    array
      'america' => int 19
      'music' => int 6
      'states' => int 5
      'bank' => int 5
  1 =>
    array
      'america' => int 19
      'home' => int 3
      'society' => int 2
      'writers' => int 2
   2 =>
    array
      'america' => int 19
      'lutheran' => int 4
      'church' => int 4
      'national' => int 4
      'cruises' => int 3

理想情况下，最终的结果会是这样的：

Ideally the end result will look like this:

array
          'america' => int 19
          'music' => int 6
          'states' => int 5
          'bank' => int 5
          'america' => int 19
          'home' => int 3
          'society' => int 2
          'writers' => int 2
          'america' => int 19
          'lutheran' => int 4
          'church' => int 4
          'national' => int 4
          'cruises' => int 3

任何解决方案？谢谢

Any solutions? thanks

推荐答案

您将不能够有相同的键值（即美国等3个按键）的关联数组。当您尝试设置这些密钥数组中，你可以简单的覆盖previous值。

You won't be able to have an associative array with the same key values (i.e. 3 keys of "America", etc.). When you try to set those keys in the array, you will simply overwrite the previous value.
