Фильтрация через JSon массив

-1

У меня есть этот JSon массивуФильтрация через JSon массив

http://paste.ofcode.org/WxS7Ra35zJZK9WtUH7T3EH

Он представляет собой коммерческое предложение от пара. Каждое предложение имеет «items_to_give» и «items_to_receive».

Я хочу, чтобы это JSON массив выглядеть следующим образом

{ 
"items_to_give": [ 
       { 
        "market_hash_name": "AWP | Asiimov (Field-Tested)", 
       }, 
       { 
        "market_hash_name": "M4A4 | Asiimov (Field-Tested)" 
       } 
       ] 
      , 

"items_to_receive": [ 
       { 
        "market_hash_name": "★ Falchion Knife | Blue Steel (Field-Tested)" 
       }      
        ] 
}

Каждый элемент имеет уникальный «ClassID» и «InstanceID», но их «market_hash_name» показывается в «описании» части массива.

Сначала я должен найти их имя, используя «classid» и «instanceid», а затем переместить его в «items_to_give» и «items_to_receive».

Вот фотография, показывающая, что я имею в виду.

Вы еще ничего не пробовали? во-первых, поскольку у вас уже есть исходный вход, превратите его в массив, выберите те вещи, которые вам нужны, и структурируйте их так, как вы хотели бы их, и поместите затем в другой контейнер, обработайте его как любой нормальный массив, затем снова закодируйте его – Ghost

я ничего не пробовал. Я не знаю, как это сделать. На данный момент у меня есть этот url = "http://api.steampowered.com/IEconService/GetTradeOffers/v0001/?key=MYKEY&get_received_offers=1&active_only=1&get_descriptions=1"; $ json = file_get_contents ($ url); $ data = json_decode ($ json, TRUE); – MHH

@Ghost Спасибо за идею, я попробую. – MHH

просто сделайте файл и протестируйте его. Я думаю, вы можете это сделать.

Результат выглядит так:

    "items_to_give": [ 
     { 
      "instanceid": "480085569",

если ответ такой же, как http://paste.ofcode.org/WxS7Ra35zJZK9WtUH7T3EH

я поставил также некоторые нужно на этом коде. потому что я тоже паровой пользователь. : D

Отлично, спасибо. Я проверил это сегодня, у меня не было времени, прежде чем тестировать его. – MHH

Сначала преобразовать JSON в PHP

$response = json_decode($json, true);

Хороший способ траверса вложенные данными являются использование array_* функции РНР. Вот почему я конвертировал в ассоциативный массив, а не в объекты.

Теперь создадим функцию для извлечения идентификаторов с помощью дают или получить:

function classIds($index, $response) 
{ 
    return array_map(function ($item) { return $item["classid"]; }, $response["response"]["trade_offers_received"][0]["items_to_" . $index]); 
}

И еще одна функция для извлечения описания для этих идентификаторов:

function descriptionForIds($ids, $response) 
{ 
    return array_map(
     // After finding matching IDs return their market hash name 
     function ($description) { 
      return [ "market_hash_name" => $description["market_hash_name"] ]; 
     }, 
     // Find matching IDs 
     array_filter(
      $response["response"]["descriptions"], 
      function ($description) use ($ids) { return in_array($description["classid"], $ids); } 
     ) 
    ); 
}

Создайте массив результатов, используя эти функции:

$result = [ 
    "items_to_give" => descriptionForIds(classIds("give", $response), $response), 
    "items_to_receive" => descriptionForIds(classIds("receive", $response), $response), 
];

И обратно в JSON:

json_encode($result);
