Question

我想在特定区域的detail array中插入data array。

例如，bdh中detail array键的值应放在bdh的{{1}}键中，替换那里的空数组首先。同样，data array中hadoop键的值应替换detail array当前所拥有的hadoop键的空数组。对data array数组中的每个键都应该进行此替换。

我如何做到这一点？

数据阵列

details

详情数组

{"data":
    {
        "categories":
        {
            "articles":
            {
                "bdh":[],
                "hadoop":[]
            },
            "videos":
            {
                "bdh Videos":[],
                "hadoop Videos":[]
            }   
        }
    }
}

<?php

    $videos = '
        {"data":
            {

    $arr_videos = json_decode($videos);
    $arr_details = json_decode($details);

    //videos hadoop
    $arr_videos->data->categories->videos->hadoop = $arr_details->details->hadoopVideos;

    print_r($arr_videos);
