php – 比较多维数组并返回数组中缺少的键

首先我们有

Array
(
    [user_authentication] => Array
        (
            [api_user_id] => xxxxxxxxxxxxxxxxxxxxxxxx
            [api_auth_token] => xxxxxxxxxxxxxxxxxxxxxx
        )

    [campaign_details] => Array
        (
            [campaign_name] => democampaign
            [campaign_category] => appsGames
            [campaign_sub_category] => Action
            [campaign_type] => cpc
            [campaign_start_date] => MM/DD/YYYY
            [campaign_end_date] => MM/DD/YYYY
            [campaign_start_time] => HH:mm
            [campaign_end_time] => HH:mm
        )

    [campaign_budget_info] => Array
        (
            [campaign_daily_budget] => 0.2
            [campaign_hourly_budget] => 0.3
            [campaign_bid] => 0.1
            [campaign_budget] => 1
        )

    [campaign_targetting_info] => Array
        (
            [campaign_os_type] => Apple
            [country_code] => IN,AF,AG
            [state_id] => Array
                (
                    [IN] => 1,2,3
                    [AF] => 4,5,6
                    [AG] => 7,8,9
                )

            [carrier] => Array
                (
                    [IN] => Tata,Aircel,RCOM,Vodafone,Airtel,Idea Cellular,Uninor,Dishnet,BSNL
                    [AF] => 
                    [AG] => 
                )

            [isp] => 
            [device_targeting] => iphone,ipad
            [conversion] => 
        )

    [campaign_creative_info] => Array
        (
            [campaign_domain] => abcd.com
            [campaign_click_url] => http://url-to-redirect-users-to-after-they-click.com/
            [campaign_banner_size] => URL640x1136
            [campaign_banner_url] => http://imageurl.com/
            [campaign_creative_type] => image
        )

    [campaign_black_list_white_list_info] => Array
        (
            [black_list_app_ids] => 5388dceb96c4b54a0844e4cb,5330b3864dab485e6219ff54
            [black_list_device_ids] => aaaaaaaa-bbbb-cccc-0000-222222221111,12f93cf2-91ed-4f8f-aae7-a0520bebdd2r
            [black_list_ip_addresses] => 123.123.12.123,10.100.100.100
            [white_list_app_ids] => 5388dceb96c4b54a0844e4cb,5330b3864dab485e6219ff54
            [white_list_device_ids] => aaaaaaaa-bbbb-cccc-0000-222222221111,12f93cf2-91ed-4f8f-aae7-a0520bebdd2r
            [white_list_ip_addresses] => 123.123.12.123,10.100.100.100
        )

)

第二个是我要比较的

Array
(
    [user_authentication] => Array
        (
            [api_user_id] => 1
            [api_auth_token] => 1
        )

    [campaign_details] => Array
        (
            [campaign_name] => 1
            [campaign_category] => 1
            [campaign_sub_category] => 1
            [campaign_type] => 1
            [campaign_start_date] => 1
            [campaign_end_date] => 1
            [campaign_start_time] => 1
            [campaign_end_time] => 1
        )

    [campaign_budget_info] => Array
        (
            [campaign_daily_budget] => 1
            [campaign_hourly_budget] => 1
            [campaign_bid] => 1
            [campaign_budget] => 1
        )

    [campaign_targetting_info] => Array
        (
            [campaign_os_type] => 1
            [country_code] => 1
            [state_id] => Array
                (
                    [IN] => 1
                    [AF] => 1
                    [AG] => 1
                )

            [carrier] => Array
                (
                    [IN] => 1
                    [AF] => 1
                    [AG] => 1
                )

            [isp] => 1
            [device_targeting] => 1
            [conversion] => 1
        )

    [campaign_creative_info] => Array
        (
            [campaign_domain] => 1
            [campaign_click_url] => 1
            [campaign_banner_size] => 1
            [campaign_banner_url] => 1
            [campaign_creative_type] => 1
        )

    [campaign_black_list_white_list_info] => Array
        (
            [black_list_app_ids] => 1
            [black_list_device_ids] => 1
            [black_list_ip_addresses] => 1
            [white_list_app_ids] => 1
            [white_list_device_ids] => 1
            [white_list_ip_addresses] => 1
        )

)

我们必须比较数组并找到第一个数组中缺少的键

我试过这个但不行

$comparemodel= array_diff_assoc($array1,$array2); 

        if($comparemodel==0){
            echo "hello";
        }
        else{
            $keys = array_keys($comparemodel);
            for ($i = 0; $i < count($keys); $i++) {
                $error_message[] = $keys[$i] . " is missing";
            }
            $model = array();
            $errors = array("error_code" => 3042,"error_message" => $error_message);
            $message = $error_message;
            $status = 0;
            $finalarray = array("modal" => $model,"errors" => $errors,"message" => $message,"status" => $status);
            echo json_encode($finalarray);

        }

它不使用这个关联数组,但它使用简单的数组.我该怎么做呢

谢谢
