从数组中获取信息

-3

我试图从该数组中获取信息，但只有来自具有值“240”的appid的信息。从数组中获取信息

（我想知道从标有 “240” 的APPID的 “playtime_2weeks”）

这是我的代码

$link = file_get_contents('http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=' . $key . '&steamid=' . $id . '&format=json'); 
$myarray = json_decode($link, true); 

$info = ($myarray['response']['games'][0]['appid']);

复制数组：

{ 
    "response": { 
     "game_count": 44, 
     "games": [ 
      { 
       "appid": 240, 
       "playtime_2weeks": 60, 
       "playtime_forever": 25979

不只是PHP的，但一般的编程明显。如果你知道如何编写一个循环，你应该知道如何解决这个问题。 – deceze

请复制/粘贴数组。 –

所以你试图解析PHP中的JSON对象？这是你坚持的部分吗？ – bsoist

那是一个JSON响应，而不是一个数组。您需要先将其转换为数组，然后查找所需的值。

$response = '{ 
    "response": { 
     "game_count": 44, 
     "games": [ 
      { 
       "appid": 240, 
       "playtime_2weeks": 60, 
       "playtime_forever": 25979 
      }, 
      { 
       "appid": 300, 
       "playtime_forever": 271 
      }, 
      .... 
      { 
       "appid": 3050, 
       "playtime_forever": 52 
      } 
     ] 

    } 
}'; 

$responseArray = json_decode($response, true); 
foreach ($responseArray['response']['games'] as $game) { 
    if ($game['appid'] == '240') { 
     echo "Playtime is: " . $game['playtime_2weeks']; 
    } 
}

array_walk($responseArray['response']['games'], function($game) { 
    if ($game['appid'] == '240') { 
     echo "Playtime is: " . $game['playtime_2weeks']; 
    } 
});
