独立JSON标签和值用PHP

Question

我曾访问我的网站上此JSON文件：

[{ 
    "01:03:2016": "410", 
    "02:03:2016": "200", 
    "03:03:2016": "380" 
}] 

我想用PHP来格式化改变这样的事情，那里的日期和计数的所有值：

[{ 
    "date": "01:03:2016", 
    "count": "410" 
}, 
{ 
    "date": "02:03:2016", 
    "count": "200" 
}, 
{ 
    "date": "03:03:2016", 
    "count": "380" 
}] 

Answer 1

PHP

$string = file_get_contents("data.json"); // your current json data 
$json_a = json_decode($string, true); 
$new_json = array(); 
foreach ($json_a as $key => $value) { 
    $new_json[] = array("date"=>$key,'count'=>$value); 
} 
echo json_encode($new_json); //output 

data.json文件（当前数据）

[{ 
    "01:03:2016": "410", 
    "02:03:2016": "200", 
    "03:03:2016": "380" 
}]
