JSON into object

Question

我使用cron作业来更新我的JSON文件，它包含以下结构；

{"country_name":"Afganistan","score":"0.00","Drinks":"Yess"},
{"country_name":"Albania","score":"3.00","Drinks":"Open"}

那么我如何让它自动变成像这样的对象，并将数据作为对象头呢？

{
     "data": [    
         {"country_name":"Afganistan","score":"0.00","Drinks":"Yess"},
         {"country_name":"Albania","score":"3.00","Drinks":"Open"}
     ]
}

Answer 1

将json数据传递给json_decode方法，如下所示

$json = '[
    { "country_name": "Afganistan", "score": "0.00", "Drinks": "Yess" },
    { "country_name": "Albania", "score": "3.00", "Drinks": "Open" }
]';


$data = ['data' => json_decode($json)];

var_dump($data);

输出

array(1) {
  ["data"]=>
  array(2) {
    [0]=>
    object(stdClass)#1 (3) {
      ["country_name"]=>
      string(10) "Afganistan"
      ["score"]=>
      string(4) "0.00"
      ["Drinks"]=>
      string(4) "Yess"
    }
    [1]=>
    object(stdClass)#2 (3) {
      ["country_name"]=>
      string(7) "Albania"
      ["score"]=>
      string(4) "3.00"
      ["Drinks"]=>
      string(4) "Open"
    }
  }
}
