如何将两个数组的字符串值与PHP成对连接? [英] how do I concatenate the string values of two arrays pairwise with PHP?

问题描述

所以我有两个数组

Array
(
[0] => test
[1] => test 1
[2] => test 2
[3] => test 3
)

和

Array
(
[0] => test
[1] => test 1
[2] => test 2
[3] => test 3
)

我想将它们组合在一起，以获得这样的数组?

I want to combine them together so I get an array like this?

Array
(
[0] => test test
[1] => test 1 test 1
[2] => test 2 test 2
[3] => test 3 test 3
)

我发现了很多功能，例如array_merge和array_combine，但是没有什么可以做的.

I have found lots of functions like array_merge and array_combine but nothing that does what I want to do.

有什么想法吗?

谢谢.

推荐答案

您可以使用array_map做到这一点:

You could do it with array_map:

$combined = array_map(function($a, $b) { return $a . ' ' . $b; }, $a1, $a2));
