两个字符串之间的差异 [英] difference between two strings

问题描述

$first = 1,2,3,4,5;
$second = 1,3,5,6;

我需要得到这两者的区别，结果如下：

$ result = 2,4,6;

I need to get difference of those two, so that result would be like:
$result = 2,4,6;

推荐答案

您的意思是

$first = "1,2,3,4,5";
$second = "1,3,5,6";

然后尝试

$first_array = explode(",", $first);
$second_array = explode(",", $second);
$result_array = array_merge(array_diff($first_array, $second_array), array_diff($second_array, $first_array));
$result = implode("," $result_array);
