PHP从数组中的JSON较低级别检索数据

Question

我知道我在这里遗漏了一些非常基本的东西：

我的json数据如下：

id: "123",
status: "SET",
  sections: [
    {
        key: "top_details",
        title: "top Details",
        fields: [
           {
             key: "order_id",
             value: "123456",
            },
            {
             key: "tracking_id",
             value: "98765",
      }
id: "456",
status: "UNSET",
    sections: [
        {
            key: "top_details",
            title: "top Details",
            fields: [
               {
                 key: "order_id",
                 value: "55555",
                },
                {
                 key: "tracking_id",
                 value: "77777",
          }

我可以使用

从顶层获取值

foreach ($json as $key=>$value)

    {


    echo $value['id'];
    echo $value['status'];

    }

但我似乎无法弄清楚如何获取'order_id'和'tracking_id'下的嵌套值。

谢谢你，原谅我的无知。

应该这样做。

foreach ($json as $key=>$value)
   {
        foreach($json['sections'] as $sections){
          foreach($sections['fields'] as $data){
             echo $data['key']."=".$data["value"];
        }
     }
    }
