我从某个网址获得以下结果。我需要从php

中的以下json响应中获取一些值

{"request":{"airport":{"requestedCode":"IXJ","fsCode":"IXJ"},"date":{"year":"2013","month":"4","day":"18","interpreted":"2013-04-18"},"hourOfDay":{"requested":"12","interpreted":12},"numHours":{"requested":"6","interpreted":6},"utc":{"requested":"false","interpreted":false},"codeType":{},"maxFlights":{"requested":"1","interpreted":1},"extendedOptions":{},"url":"https://api.flightstats.com/flex/flightstatus/rest/v2/json/airport/status/IXJ/dep/2013/04/18/12"},"appendix":{"airlines":[{"fs":"G8","iata":"G8","icao":"GOW","name":"GoAir","active":true}],"airports":[{"fs":"BOM","iata":"BOM","icao":"VABB","name":"Chhatrapati Shivaji International Airport","city":"Mumbai","cityCode":"BOM","countryCode":"IN","countryName":"India","regionName":"Asia","timeZoneRegionName":"Asia/Kolkata","localTime":"2013-04-18T08:37:27.791","utcOffsetHours":5.5,"latitude":19.095508,"longitude":72.874969,"elevationFeet":27,"classification":1,"active":true,"delayIndexUrl":"https://api.flightstats.com/flex/delayindex/rest/v1/json/airports/BOM?codeType=fs","weatherUrl":"https://api.flightstats.com/flex/weather/rest/v1/json/all/BOM?codeType=fs"},{"fs":"SXR","iata":"SXR","icao":"VISR","name":"Srinagar Airport","city":"Srinagar","cityCode":"SXR","countryCode":"IN","countryName":"India","regionName":"Asia","timeZoneRegionName":"Asia/Kolkata","localTime":"2013-04-18T08:37:27.791","utcOffsetHours":5.5,"latitude":34.002308,"longitude":74.762631,"elevationFeet":5436,"classification":4,"active":true,"delayIndexUrl":"https://api.flightstats.com/flex/delayindex/rest/v1/json/airports/SXR?codeType=fs","weatherUrl":"https://api.flightstats.com/flex/weather/rest/v1/json/all/SXR?codeType=fs"},{"fs":"IXJ","iata":"IXJ","icao":"VIJU","name":"Satwari Airport","city":"Jammu","cityCode":"IXJ","countryCode":"IN","countryName":"India","regionName":"Asia","timeZoneRegionName":"Asia/Kolkata","localTime":"2013-04-18T08:37:27.387","utcOffsetHours":5.5,"latitude":32.68077,"longitude":74.842824,"elevationFeet":1029,"classification":4,"active":true,"delayIndexUrl":"https://api.flightstats.com/flex/delayindex/rest/v1/json/airports/IXJ?codeType=fs","weatherUrl":"https://api.flightstats.com/flex/weather/rest/v1/json/all/IXJ?codeType=fs"}],"equipments":[{"iata":"320","name":"Airbus Industrie A320","turboProp":false,"jet":true,"widebody":false,"regional":false}]},"flightStatuses":[{"flightId":294315800,"carrierFsCode":"G8","flightNumber":"387","departureAirportFsCode":"IXJ","arrivalAirportFsCode":"BOM","departureDate":{"dateLocal":"2013-04-18T15:15:00.000","dateUtc":"2013-04-18T09:45:00.000Z"},"arrivalDate":{"dateLocal":"2013-04-18T18:05:00.000","dateUtc":"2013-04-18T12:35:00.000Z"},"status":"S","schedule":{"flightType":"J","serviceClasses":"RFJY","restrictions":"","uplines":[{"fsCode":"BOM","flightId":294284559},{"fsCode":"SXR","flightId":294354303}]},"operationalTimes":{"publishedDeparture":{"dateLocal":"2013-04-18T15:15:00.000","dateUtc":"2013-04-18T09:45:00.000Z"},"publishedArrival":{"dateLocal":"2013-04-18T18:05:00.000","dateUtc":"2013-04-18T12:35:00.000Z"},"scheduledGateDeparture":{"dateLocal":"2013-04-18T15:15:00.000","dateUtc":"2013-04-18T09:45:00.000Z"},"scheduledGateArrival":{"dateLocal":"2013-04-18T18:05:00.000","dateUtc":"2013-04-18T12:35:00.000Z"}},"flightDurations":{"scheduledBlockMinutes":170},"airportResources":{"arrivalTerminal":"1B"},"flightEquipment":{"scheduledEquipmentIataCode":"320"}}]}

就像我只想获取carrierFsCode，flightNumber，departureAirportFsCode，arrivalAirportFsCode，departureDate，arrivalDate，status，scheduledGateDeparture，flightDurations，flightDurations

json响应中有许多航班状态。有人可以帮助我获得这些价值。

Answer 1

你似乎已经使用json-decode对此进行了标记..有什么特别的原因，这对你不起作用吗？

$json = ''; //your json string here
$obj = json_decode($json);

var_dump($obj);

编辑：更新答案，以免使讨论延长这么久。为了获得所有状态，您需要为flightStatuses数组运行foreach循环。

foreach ($obj->flightStatuses as $flightstatus) {
    echo $flightstatus->flightId,"<br>";
}

Answer 2

您可以使用json_decode将此JSON转换为关联数组。然后，您可以轻松选择所需的值。假设您的JSON包含在名为$ data

的变量中

$associative_array = json_decode($data, true);
$carrierFsCode = $associative_array['carrierFsCode'];
$flightNumber = $associative_array['flightNumber'];

...等

获取Json值
