Question

我对数组和多维数组很新，我想知道如何比较两个数组的key =＆gt;值对（或者包含数组的两个不同键的单个数组？）并取消设置key =＆gt;每个数组中与键和值匹配的值。

示例数组：

Array
(
    [from] => Array
        (
            [active] => 1
            [airport_ids] => 
            [group_name] => test adgrp
            [zone_id] => 12
            [creation_time] => 1234567890
        )

    [to] => Array
        (
            [active] => 1
            [airport_ids] => 
            [group_name] => test adgroup
            [zone_id] => 2
            [group_email] => test@group.com
        )

)

因此，from是基本键数组，to是比较键数组。我想遍历to和from个键组，找到匹配的键，并比较两个匹配项的值。

如果key =＆gt;值对匹配，则取消设置to和from键阵列中的key =＆gt;值。

如果to中找到的密钥不在from中，请将其保留在to数组中。但是，如果在from中找不到to中找不到的密钥，请将其从from密钥数组中取消设置。

将上述数组转换为：

Array
(
    [from] => Array
        (
            [group_name] => test adgrp
            [zone_id] => 12
        )

    [to] => Array
        (
            [group_name] => test adgroup
            [zone_id] => 2
            [group_email] => test@group.com
        )

)

@Meta尝试以下概念：

<?php
    $arr1 = 
            array
            (
                "from" => array
                    (
                        "active" => 1,
                        "airport_ids" => null,
                        "group_name" => "test adgrp",
                        "zone_id" => 12,
                        "creation_time" => 1234567890
                    ),

                "to" => array
                    (
                        "active" => 1,
                        "airport_ids" => null,
                        "group_name" => "test adgroup",
                        "zone_id" => 2,
                        "group_email" => "test@group.com"
                    )

            );

    echo "<pre>";
    print_r($arr1); //before

    foreach($arr1["from"] as $key => $value) {
      foreach($arr1["to"] as $key1 => $value1) {
        if($key == $key1 && $value == $value1){
            unset($arr1["from"][$key], $arr1["to"][$key1]);
            break;
        }

      }
    }
    echo "<pre>";
    print_r($arr1); //after

比较两个数组并使用php取消数组中的任何匹配对？
