充分利用2个数组唯一值 [英] Getting unique values from 2 arrays

问题描述

我有2个阵列，我试图只从他们那里得到的唯一值。所以，我不只是想删除重复的，我其实是想删除这两个副本。

I have 2 arrays that I'm trying to get the unique values only from them. So I'm not just trying to remove duplicates, I'm actually trying to remove both duplicates.

所以，如果我得到了2个数组是这样的：

So if I'm getting the 2 arrays like this:

$array1 = array();
$array2 = array();

foreach($values1 as $value1){ //output: $array1 = 10, 15, 20, 25;
    $array1[] = $value1;
}   

foreach($values2 as $value2){ //output: $array2 = 10, 15, 100, 150;
    $array2[] = $value2;
}

我在寻找最终的输出是

The final output I'm looking for is

$output = 20, 25, 100, 150;

任何巧妙的方法能完成这一操作？

Any neat way to getting this done?

推荐答案

其他的答案是正确的轨道上，但是的 和array_diff 只在一个方向工作 - 即它返回存在给定的第一阵列中不在任何其他的值。

The other answers are on the right track, but array_diff only works in one direction -- ie. it returns the values that exist in the first array given that aren't in any others.

您想要做的就是让不同的两个方向，然后区别合并到一起：

What you want to do is get the difference in both directions and then merge the differences together:

$array1 = array(10, 15, 20, 25);
$array2 = array(10, 15, 100, 150);
$output = array_merge(array_diff($array1, $array2), array_diff($array2, $array1));
// $output will be (20, 25, 100, 150);
