通过json数组过滤
它代表了蒸汽的交易报价。每个优惠都有“items_to_give”和“items_to_receive”。
我希望这个json数组看起来像这样
{
"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)"
}
]
}
每个项目都有唯一的“classid”和“instanceid”，但它们的“market_hash_name”显示在数组的“描述”部分中。
首先，我必须使用“classid”和“instanceid”找到他们的名字，然后将其移至“items_to_give”和“items_to_receive”。
这张照片显示了我的意思。

Just make a file and test it. I think you can do it.
The Result is like this:

答案 1 :(得分：0)
首先将您的JSON转换为PHP
$response = json_decode($json, true);
遍历嵌套数据的好方法是使用PHP的array_*函数。这就是我转换为关联数组而不是对象的原因。
现在创建一个函数来通过给或接收来获取ID：
function classIds($index, $response)
{
return array_map(function ($item) { return $item["classid"]; }, $response["response"]["trade_offers_received"][0]["items_to_" . $index]);
}
另一个获取这些ID描述的函数：
function descriptionForIds($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); }
)
);
}
使用以下函数构建结果数组：
$result = [
"items_to_give" => descriptionForIds(classIds("give", $response), $response),
"items_to_receive" => descriptionForIds(classIds("receive", $response), $response),
];
回到JSON：
json_encode($result);
