json_decode雙陣列

-2

首先即時通訊新英的心不是我的主要語言，所以請善待=）json_decode雙陣列

林與蒸汽-API的事情工作ATM和我不能讓下面的工作：

我可以通過描述訪問json，但我也需要訪問資產。第一個資產有一個組合標記，並且是描述中的第一個項目。希望你能理解我由xD

現在我需要兩個結合，這樣我可以有每個項目由assetid ..

這裏是我的JSON：

"assets":[ 
     {"appid":"730", 
     "contextid":"2", 
     "assetid":"9700979102", 
     "classid":"310783254", 
     "instanceid":"480085569", 
     "amount":"1"}, 
     {"appid":"730", 
     "contextid":"2", 
     "assetid":"9700979062", 
     "classid":"2050552817", 
     "instanceid":"188530139", 
     "amount":"1"} 
    ], 
    "descriptions":[ 
     {"appid":730,

     "market_actions":[], 
     "commodity":0, 
     "market_tradable_restriction":7, 
     "marketable":1,"tags":[]}

和我的PHP代碼..

$InventarUrl = "http://steamcommunity.com/inventory/".$steamID."/730/2?l=german"; 
$inven = file_get_contents($InventarUrl); 
$invenDeco = json_decode($inven); 

foreach ($invenDeco->{'assets'} as $key2 => $obj2) { 
    $assetID = $obj2->assetid; 
} 

foreach ($invenDeco->{'descriptions'} as $key => $obj) { 

    $zustand = $obj->descriptions[0]->value; 

    if (strpos($zustand, "Zustand:") !== false) { 
     $marketPrice = file_get_contents("http://steamcommunity.com/market/priceoverview/?currency=3&appid=730&market_hash_name=" . urlencode($obj->market_hash_name)); 
     $marketPriceDeco = json_decode($marketPrice); 
     $itemName = $obj->name; 
     if(strpos($obj->name, "StatTrak™")) { 
      $stattrak = 1; 
     } else { 
      $stattrak = 0; 
     } 
      $ItemImageLink = $obj->icon_url; 
      $ItemPrice = str_replace(",",".",$marketPriceDeco->median_price); 
     } 
}

我只需要知道，我怎麼能結合兩者的foreach數組，我可以用正確的項目由assetid結合..

謝謝！

你能格式化你的json和php代碼嗎？這種方式幾乎不可讀。 –

你可以使用一個for循環，而不是一個foreach。

for ($i = 0; $i < count($invenDeco->assets); $i++) { 
    $asset  = $invenDeco->assets[$i]; 
    $description = $invenDeco->descriptions[$i]; 
    // Do something with $asset and $description 
}

非常感謝你！ – hublrs

我假設「assets」和「description」數組的大小相同。

var arr = []; 
for(var i = 0; i < data.assets.length; i++) { 
    var combined = new Object(); 
    combined.asset = data[i].asset; 
    combined.description = data[i].description; 
    arr.push(combined); 
}

所以現在arr是一個javascript對象數組。每個對象都有一個assets屬性和一個description屬性。你應該能夠訪問這樣

var asset = arr[0].asset; 
var description = arr[0].description; // etc...

我沒有兩個JSON數組相當結合成1個數組，但現在每一塊資產和描述數據的將被存儲在一個對象。因此，我們有，

arr[0].asset.appid == arr[0].description.appid; // TRUE

謝謝你的回答，但我需要在PHP – hublrs
