通过json阵列进行过滤
通过json阵列进行过滤
提问于 2016-02-03 02:22:20
它代表的是来自蒸汽的贸易报价。每个报价都有"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)"
}
]
}每个项目都有独特的“分类”和"instanceid“，但是它们的"market_hash_name”显示在数组的“描述”部分。
首先，我必须找到他们的名字使用“分类”和"instanceid“，而不是移动到"items_to_give”和"items_to_receive“。
这是我的意思的照片。

只需制作一个文件并测试它。我觉得你能做到。
结果如下：

首先将JSON转换为PHP
$response = json_decode($json, true);遍历嵌套数据的一个好方法是使用PHP的array_*函数。这就是为什么我转换为关联数组而不是对象的原因。
现在创建一个函数，通过给予或接收来获取ID。
function classIds($index, $response)
{
return array_map(function ($item) { return $item["classid"]; }, $response["response"]["trade_offers_received"][0]["items_to_" . $index]);
}和另一个函数来获取这些ID的描述：
function descriptionForIds($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),
];然后回到JSON：
