PHP diff数组值和非键diff

Question

我有一个问题，我希望，我可以帮助解决这个问题。

我的问题是我得到了这两个数组

$array1 = ["test1" => "red", "test2" => "blue", "test3" => "green"];
$array2 = ["test1" => "red", "test2" => "blue", "test3" => "blue"];

正如你可以看到的不同是数组键test3的值是不同的，我的问题是我需要知道键test3有一个不同，并且从$array1到$array2

我试过array_diff和array_intersect，但这不是我想要的。我有一个产品，我需要知道从上次运行以来有什么变化，如果我使用on of this命令，它不会告诉我diff在哪里，而是diff是什么。

有没有人能帮我解释一下我能做些什么，或者说有一个函数可以处理这个问题？

Answer 1

<?php
    $array1 = array("a" => "green", "b" => "brown", "c" => "blue", "d" => "red");
    $array2 = array("a" => "green", "b" => "brown", "c" => "blue", "d" => "yellow");
    $result = array_diff_assoc($array1, $array2);
    echo print_r($result, true);
?>

Answer 2

<?php
$array1 = ["test1" => "red", "test2" => "blue", "test3" => "green"];
$array2 = ["test1" => "red", "test2" => "blue", "test3" => "blue"];

$result=array_diff($array1,$array2);
print_r($result);
?>

This shud work
o/p : Array ( [test3] => green )
