从另一个数组替换数组中的值

Question

我有这个数组结构：

stdClass Object
(
    [carrierFsCode] => VX
    [flightNumber] => 925
    [departureAirportFsCode] => LAX
    [arrivalAirportFsCode] => SFO
    [stops] => 0
    [departureTerminal] => 3
    [arrivalTerminal] => 2
    [departureTime] => 2014-04-28T07:00:00.000
    [arrivalTime] => 2014-04-28T08:20:00.000
    [flightEquipmentIataCode] => 32S
    [isCodeshare] => 
    [isWetlease] => 
    [serviceType] => J
    [serviceClasses] => Array
        (
            [0] => F
            [1] => J
            [2] => Y
        )

    [trafficRestrictions] => Array
        (
        )

    [codeshares] => Array
        (
            [0] => stdClass Object
                (
                    [carrierFsCode] => SQ
                    [flightNumber] => 1407
                    [serviceType] => J
                    [serviceClasses] => Array
                        (
                            [0] => R
                            [1] => F
                            [2] => J
                            [3] => Y
                        )

                    [trafficRestrictions] => Array
                        (
                            [0] => Q
                        )

                    [referenceCode] => 10594616
                )

        )

    [referenceCode] => 979-1740743--
)
stdClass Object
(
    [carrierFsCode] => SQ
    [flightNumber] => 1407
    [departureAirportFsCode] => LAX
    [arrivalAirportFsCode] => SFO
    [stops] => 0
    [departureTerminal] => 3
    [arrivalTerminal] => 2
    [departureTime] => 2014-04-28T07:00:00.000
    [arrivalTime] => 2014-04-28T08:20:00.000
    [flightEquipmentIataCode] => 32S
    [isCodeshare] => 1
    [isWetlease] => 
    [serviceType] => J
    [serviceClasses] => Array
        (
            [0] => R
            [1] => F
            [2] => J
            [3] => Y
        )

    [trafficRestrictions] => Array
        (
            [0] => Q
        )

    [operator] => stdClass Object
        (
            [carrierFsCode] => VX
            [flightNumber] => 925
            [serviceType] => J
            [serviceClasses] => Array
                (
                    [0] => F
                    [1] => J
                    [2] => Y
                )

            [trafficRestrictions] => Array
                (
                )

        )

    [codeshares] => Array
        (
        )

    [referenceCode] => 979-1740743--10594616
)

这个数组结构：

Array
(
    [0] => stdClass Object
        (
            [fs] => SQ
            [iata] => SQ
            [icao] => SIA
            [name] => Singapore Airlines
            [active] => 1
        )
    [1] => stdClass Object
        (
            [fs] => VX
            [iata] => VX
            [icao] => VRD
            [name] => Virgin America
            [active] => 1
        )

）

基本上我想做的是获取第一个数组并在第二个数组中找到匹配的IATA/FS代码，并将其替换为ICAO代码。例如，对于第一个数组，我想用VX替换VRD。我希望能够将相同的概念应用于其他航空公司/航线......不仅仅是VX。

如果有帮助，我将从JSON返回获取此信息：http://pastebin.com/2w0kQQ26

我调查了array_replace()，但由于我的PHP技能几乎没有，我不知道如何继续。

如果有人能指出我正确的方向，我会很感激。

Answer 1

array1是您的第一个数组，array2是您描述的第二个数组。

$comp_arr = array()
foreach ($array2 as $arr) {
  $comp_arr[$arr[fs]] = $arr[icao];
}

foreach($array1 as $key => $arr){
  if(array_key_exist($arr[carrierFsCode], $comp_arr){
       $array1[$key][carrierFsCode] = $comp_arr[$arr[carrierFsCode]];
  }
}
