PHP json数组，并从深度嵌套的数组中获取一些键值-php问题

php json array of arrays and get some key values from deep nested(PHP json数组，并从深度嵌套的数组中获取一些键值)

本文介绍了PHP json数组，并从深度嵌套的数组中获取一些键值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个从API获取的JSON数据，我想为每个属性获取/访问code和values要存储到表中的代码，因为表列和值对于每个记录都是动态的。我不需要存储json值中的附件和Total。我想以INSERT INTO(ID，TrackingNumber，CustomerFull)值(json值)的形式存储到表中。任何代码引爆器、php解决方案或提示都将非常有用。

JSON

首先，您应该将推荐答案转换为数组，然后使用循环(Foreach、For、While...)并获得相应的价值，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":[
