問題描述

我已多次解析 JSON 數據，但由于某種原因，無法找到嵌套數據時要使用的正確語法.我正在嘗試從此 JSON 解析資產"，但無論我嘗試什么，都會繼續獲得為 foreach() 提供的無效參數.

I have parsed JSON data numerous times but for some reason cannot find the correct syntax to use when the data is nested. I am trying to parse the "assets" from this JSON but continue to get a invalid argument supplied foreach() regardless of what I try.

   "3435":{
      "name":"COLO-1014-SJ1",
      "nickname":"US-SJC-004",
      "type":"Colocated Server",
      "location":"San Jose:55 S Market",
      "assets":{
         "CPU":[
            {
               "model":"Intel E3 1270"
            }
         ],
         "Hard Drives":[
            {
               "model":"Western Digital 500GB RE4 ABYX SATA"
            },
            {
               "model":"Western Digital 500GB RE4 ABYX SATA"
            },
            {
               "model":"Kingston 240GB SSD"
            }
         ],
         "RAM":[
            {
               "model":"Super Talent 4GB DDR3 1333 ECC"
            },
            {
               "model":"Super Talent 4GB DDR3 1333 ECC"
            },
            {
               "model":"Super Talent 4GB DDR3 1333 ECC"
            },
            {
               "model":"Super Talent 4GB DDR3 1333 ECC"
            }
         ],

我希望它類似于......

I would expect it to be something along the lines of...

$json = json_decode($jsondata, true);

foreach ($json as $item)
{
    foreach ($item['assets']->RAM as $asset)
    {
        echo $asset->model;
    }

推薦答案

來自php官方文檔:http://php.net/manual/fr/function.json-decode.php

第二個 func arg 用于關聯數組返回.如果您更喜歡在對象上操作關聯數組，則可以使用它.

The 2nd func arg is for assoc array return. You can use it if you prefer to manipulate assoc array over object.

但你實際上在循環中混合了數組和對象.

But you actually mix array and object in your loop.

如果您將參數保持在 TRUE，請使用 $item['assets']['RAM']

If you keep the arg at TRUE, please use $item['assets']['RAM']
