php - php array_filter如果时间在1小时内

我正试图找出如何根据比较筛选对象。
我得到一个像这样的物体，虽然有15个结果…

stdClass Object
(
    [FlightInfoExResult] => stdClass Object
        (
            [next_offset] => 15
            [flights] => Array
                (
                    [0] => stdClass Object
                        (
                            [faFlightID] => SWA2078-1499232401-airline-0885
                            [ident] => SWA2078
                            [aircrafttype] => B738
                            [filed_ete] => 03:00:00
                            [filed_time] => 1499232401
                            [filed_departuretime] => 1499477700
                            [filed_airspeed_kts] => 423
                            [filed_airspeed_mach] =>
                            [filed_altitude] => 0
                            [route] =>
                            [actualdeparturetime] => 0
                            [estimatedarrivaltime] => 1499489100
                            [actualarrivaltime] => 0
                            [diverted] =>
                            [origin] => KPHX
                            [destination] => KMKE
                            [originName] => Phoenix Sky Harbor Intl
                            [originCity] => Phoenix, AZ
                            [destinationName] => General Mitchell Intl

我需要过滤这个对象，所以只返回[flights]，其中[filed_departuretime]在查询结果$time = strtotime($item['departure_time']);的1小时内。
通过这样做：

abs($object->filed_departuretime - $time) <= 3600)

希望这一切都是有意义的，谢谢你的帮助：）我真的不知道数组过滤器是如何工作的，所以这是我目前所拥有的…

//set flight identity
$ident = $item['airline'].$item['flight_number'];
$date = date('Y-m-d H:i:s');
$time = strtotime($item['departure_time']);

//get flightaware results
$flightAwareResult = FlightInfoEx($ident);

/*$flightResult = array_filter(
  $flightAwareResult,
);*/

最佳答案

数组过滤器接受一个数组并通过一个函数传递每个元素。它只保留函数返回真值的元素。例子：

//set flight identity
$ident = $item['airline'].$item['flight_number'];
$date = date('Y-m-d H:i:s');
$time = strtotime($item['departure_time']);

//get flightaware results
$flightAwareResult = FlightInfoEx($ident);
$filtered_array = array_filter($flightAwareResult->FlightInfoExResult->flights, function ($value) use ($time) {
      return  $time - $value->filed_departuretime) <= 3600;
});
