我有这个包含四个文本消息的 xml，并且我已将其转换为一个数组。

xml

数组

我有另一个xml doc 2，我只更改了一个值-第一个值是address="0800000"，第二个是address="0900000"。当我使用比较两个数组时

include "xml2array.php";
$contents = file_get_contents('sms.xml');//Or however you what it
$result = xml2array($contents);
//print_r($result);

$contents_ = file_get_contents('smsz.xml');//Or however you what it
$result_ = xml2array($contents_);
//print_r($result_);

$result_diff = array_diff($result, $result_);

print_r($result_diff);

我明白了，这不是我所期待的。

大批 （ ）

我期待类似的东西

Array
(
    [1] => 0900000
)

您有一个多维数组，而 array_diff 仅支持一维。

从有关array_diff的手册中：

This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using array_diff($array1[0], $array2[0]);.

目前还不清楚你到底想对我做什么。但array_diff()仅根据文档比较一维数组。所以是的，它会失败......

注意：在文档的注释中是如何检查多维数组的示例。
