我想從那時起獲取 APIhttps://www.travel-advisory.info/api我已經編寫了我的代碼 $curl = new CurlService(); $response = $curl->to('https://www.travel-advisory.info/api')->get(); throw_if(!$response, Exception::class, 'Terjadi kesalahan: Data tidak dapat diperoleh'); $data = json_decode($response); echo $data->data;這是 API 響應的示例 "data": { "AD": { "iso_alpha2": "AD", "name": "Andorra", "continent": "EU", "advisory": { "score": 2.79999999999999982236431605997495353221893310546875, "sources_active": 4, "message": "", "updated": "2020-08-04 07:21:19", "source": "https://www.travel-advisory.info/andorra" } }, "AE": { "iso_alpha2": "AE", "name": "United Arab Emirates", "continent": "AS", "advisory": { "score": 3.100000000000000088817841970012523233890533447265625, "sources_active": 7, "message": "", "updated": "2020-08-04 07:21:19", "source": "https://www.travel-advisory.info/united-arab-emirates" } }, "AF": { "iso_alpha2": "AF", "name": "Afghanistan", "continent": "AS", "advisory": { "score": 5, "sources_active": 10, "message": "", "updated": "2020-08-04 07:21:19", "source": "https://www.travel-advisory.info/afghanistan" } }, "AG": { "iso_alpha2": "AG", "name": "Antigua and Barbuda", "continent": "NA", "advisory": { "score": 3, "sources_active": 3, "message": "", "updated": "2020-08-04 07:21:19", "source": "https://www.travel-advisory.info/antigua-and-barbuda" } }, "AI": { "iso_alpha2": "AI", "name": "Anguilla", "continent": "NA", "advisory": { "score": 3, "sources_active": 3, "message": "", "updated": "2020-08-04 07:21:19", "source": "https://www.travel-advisory.info/anguilla" } } }我的問題是如何過濾continent : "AS"？p

您可以使用json_decode數組標志和array_filter方法，如下所示：
$data = (json_decode($response, true))['data'];
$as = array_filter($data, function($item) {
return $item['continent'] === 'AS';
});
另請注意，上面示例中給出的 json 需要全部用大括號括起來，如下所示：
{
"data": {
...
}

如果大陸值與“AS”匹配，您可以循環遍歷每個對象并推送到新數組。
使用$key => $value允許您保留索引。
例子：
$filtered = [];
foreach ( $data->data as $key => $value )
{
if ( $value->continent === "AS" )
{
$filtered[$key] = $value;
}
}
print_r($filtered);
會給你：
[AE] => stdClass Object
(
[iso_alpha2] => AE
[name] => United Arab Emirates
[continent] => AS
[advisory] => stdClass Object
(
[score] => 3.1
[sources_active] => 7
[message] =>

)
[AF] => stdClass Object
(
[iso_alpha2] => AF
[name] => Afghanistan
[continent] => AS
[advisory] => stdClass Object
