php json array of arrays 并从深层嵌套中获取一些键值

Question

我有一个从 API 获取的 JSON 数据，我想 get/access 为每个 AttributeValues code 和 values 存储到表，代码作为表的列和值对于每个记录都是动态的。我不需要存储 json 值中的 Attachements 和 Total。我想存储到表中作为插入到 (ID、TrackingNumber、CustomerFull) 值（json 值）。任何 codeigniter 或 php 解决方案或提示都非常适用。

 {
    "Values": [{
            "AttributeValues": [{
                    "ID": 0,
                    "Name": "ID",
                    "Values": [
                        "720"
                    ],
                    "DataType": "Number",

首先，您应该将 JSON 转换为数组，然后使用循环（foreach、for、while...）并相应地获取值，如下所示：

<?php 

 $json = '{
  "Values":[
    {
        "AttributeValues":[
            {
            "ID":0,
            "Name":"ID",
            "Values":[
                "720"
            ],
            "DataType":"Number",
            "Code":"ID",
            "IsVisible":true,
            "IsValueEmptyOrNull":false,
            "IsDefault":true
            },
            {
            "ID":0,
            "Name":"Tracking Number",
            "Values":[
                "xxxx/1094/180730/1"
            ],
            "DataType":"String",
            "Code":"TrackingNumber",
            "IsVisible":true,
            "IsValueEmptyOrNull":false,
            "IsDefault":true
            },
            {
            "ID":0,
            "Name":"Customer Full",
            "Values":[

            "IsVisible":true,
            "IsValueEmptyOrNull":false,
            "IsDefault":true
            },
            {
