json_decode with double array

Question

首先我是新的，英语不是我的主要语言，所以请善待=(

我正在使用

蒸汽 api 事物 atm，我无法进行以下工作：

我可以访问带有描述的 json，但我也需要访问资产。第一个资产有一个资产 ID，用于描述中的第一项。希望你理解我xD

现在我需要将两者结合起来，以便我可以为每个项目提供一个资产 ID。

这是我的 json：

    "assets":[
        {"appid":"730",
        "contextid":"2",
        "assetid":"9700979102",

和我的PHP代码..

$InventarUrl = "http://steamcommunity.com/inventory/".$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，我如何组合两个 foreach 数组，我可以将 assetid 与正确的项目组合在一起。

谢谢！

Answer 1

您可以使用

for循环而不是foreach。

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

Answer 2

我假设"assets"和"description"数组的大小相同。

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);
}

所以现在arr是一个JavaScript对象的数组。每个对象都有一个资产属性和一个描述属性。您应该能够像这样访问

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

我没有将两个 json 数组完全合并为 1 个数组，但现在每条资产和描述数据都将存储在一个对象中。所以我们有，

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