訪問json.parse多維數組php

Question

我有以下json：-

{
    "firstName": "Jhon",
    "lastName": "Doe",
    "username": "jhon",
    "avatar": "localhost/uploads/avatars/default.jpg",
    "language": "ar",
    "birth_date": "2017-11-22 00:00:00",
    "weight_chart": [],
    "health_status": {
        "id": 130,
        "user_id": 258,
        "weight": 95,
        "height": 171,
    },

我解碼了上面的json

$user = json_decode($response);

現在，我可以使用以下命令打印名字：$ user-> firstName

我的問題是：

• 我可以不解碼就訪問json值嗎？
• 如何訪問“ health_status”值id，權重...？

Answer 1

您的json格式錯誤，請嘗試以下結構：

$str = '{
    "firstName": "Jhon",
    "lastName": "Doe",
    "username": "jhon",
    "avatar": "localhost/uploads/avatars/default.jpg",
    "language": "ar",
    "birth_date": "2017-11-22 00:00:00",
    "weight_chart": [],
    "health_status": {
        "id": 130,
        "user_id": 258,
        "weight": 95,
        "height": 171
    }
}';

$obj = json_decode($str);
echo $obj->firstName.' - ';
echo $obj->health_status->id.' - ';
echo $obj->health_status->weight; 

回應： Jhon - 130 - 95
