修改PHP雄辯收藏

Question

我有PHP（雄辯的集合）生成此JSON數據

{ 
    "1498454460": [ 
     { 
     "value_0": 22.7 
     }, 
     { 
     "value_2": 23 
     } 
    ], 
    "1498454640": [ 
     { 
     "value_0": 22.8 
     }, 
     { 
     "value_1": 53 
     }, 
     { 
     "value_2": 23 
     } 
    ] 
} 

我的目標是獲得這些數據格式與PHP：

{ 
    "timestamp": 1498454460, 
    "value_0": 22.7, 
    "value_2": 23 
}, 
{ 
    "timestamp": 1498454640, 
    "value_0": 22.8, 
    "value_1": 53, 
    "value_2": 23 
} 

我的腦子被鎖定我看不到溶液...：/

解碼的JSON成陣列，迭代陣列上方和創建這樣的期望結構：

<?php 
$json = ' 
{ 
    "1498454460": [ 
     { 
     "value_0": 22.7 
     }, 
     { 
     "value_2": 23 
     } 
    ], 
    "1498454640": [ 
     { 
     "value_0": 22.8 
     }, 
     { 
     "value_1": 53 
     }, 
     { 
     "value_2": 23 
     } 
    ] 
}'; 

$result = array(); 
foreach (json_decode($json, true) as $key => $value) { 
    $item = array(); 
    $item['timestamp'] = $key; 
    foreach ($value as $value2) { 
     $item = array_merge($item, $value2); 
    } 
    $result[] = $item; 
} 

echo json_encode($result); 
die();
