如何在PHP SoapClient（）中重复对象0次或更多次？

Question

I'm using something called Radixx ConnectPoint (SOAP) and I have run into a slight snag with how to go about requesting information correctly. Apologies if this is obvious; I am very new to SOAP.

For testing purposes I have this XML example that the API developer sent me to model my request after:

POST http://xxx.connectpoint.uat.radixx.com/ConnectPoint.Pricing.svc HTTP/1.0
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: "http://tempuri.org/IConnectPoint_Pricing/RetrieveFareQuote"
Content-Length: 4076
Host: xxx.connectpoint.uat.radixx.com
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.2 (Java/1.8.0_77)

I have removed the identifying carrier codes and replaced them with xxx. The GUID security code is not valid anymore so I have left it in.

$data->CurrencyOfFareQuote = "USD";
$data->CorporationID = -214;
$data->FareFilterMethod = "NoCombinabilityRoundtripLowestFarePerFareType";
$data->FareGroupMethod = "WebFareTypes";
$data->InventoryFilterMethod = "Available";
$data->ClientIPAddress = "?"; // Optional
$data->HistoricUserName = "?"; // Optional
$data->PromotionalCode = null;
$data->IataNumberOfRequestor = null;
$data->FareQuoteDetails->FareQuoteDetail->Origin = "BRL";
$data->FareQuoteDetails->FareQuoteDetail->Destination = "ORD";
$data->FareQuoteDetails->FareQuoteDetail->UseAirportsNotMetroGroups = false;
$data->FareQuoteDetails->FareQuoteDetail->UseAirportsNotMetroGroupsAsRule = false;
$data->FareQuoteDetails->FareQuoteDetail->UseAirportsNotMetroGroupsForForm = false;
$data->FareQuoteDetails->FareQuoteDetail->UseAirportsNotMetroGroupsForTo = false;
$data->FareQuoteDetails->FareQuoteDetail->DateOfDeparture = "2016-11-20";
$data->FareQuoteDetails->FareQuoteDetail->FareTypeCategory = 1;
$data->FareQuoteDetails->FareQuoteDetail->FareClass = null;
$data->FareQuoteDetails->FareQuoteDetail->FareBasisCode = null;
$data->FareQuoteDetails->FareQuoteDetail->Cabin = null;
$data->FareQuoteDetails->FareQuoteDetail->LFID = -214;
$data->FareQuoteDetails->FareQuoteDetail->OperatingCarrierCode = null;
$data->FareQuoteDetails->FareQuoteDetail->MarketingCarrierCode = null;
$data->FareQuoteDetails->FareQuoteDetail->NumberOfDaysBefore = 0;
$data->FareQuoteDetails->FareQuoteDetail->NumberOfDaysAfter = 0;
$data->FareQuoteDetails->FareQuoteDetail->LanguageCode = "en";
$data->FareQuoteDetails->FareQuoteDetail->TicketPackageID = 1;

$quote = $pricing->RetrieveFareQuote(array("RetrieveFareQuoteRequest" => $data));
print_r($quote);

Once I ran a print_r I saw that I forgot to add the FareQuoteRequestInfos object, but after looking at the XML I am unsure how to add it in. From the XML, it looks like I also have to do the same thing to the FareQuoteDetail object, as it needs to be able to repeat.

How would I do such a thing? Do I add them as arrays?

For reference, here is the print_r result:

stdClass Object
(
    [RetrieveFareQuoteResult] => stdClass Object
        (
            [CommissionIncluded] => 
            [Exceptions] => stdClass Object
                (
                    [ExceptionInformation.Exception] => stdClass Object
                        (
                            [ExceptionCode] => 9989
                            [ExceptionDescription] => RetrieveFareQuote/FareQuoteDetails[0]/FareQuoteRequestInfos: cannot be NULL and collection count must be between 1 and 20
                            [ExceptionSource] => RetrieveFareQuote
                            [ExceptionLevel] => Critical
                        )

                )

            [FlightSegments] => stdClass Object
                (
                )

            [LegDetails] => stdClass Object
                (
                )

            [RequestedCorporationID] => 0
            [RequestedCurrencyOfFareQuote] => 
            [RequestedFareFilterMethod] => 0
            [RequestedGroupMethod] => 0
            [RequestedIataNumber] => 
            [RequestedInventoryFilterMethod] => 0
            [RequestedPromotionalCode] => 
            [RequestedReservationChannel] => 0
            [SegmentDetails] => stdClass Object
                (
                )

            [TaxDetails] => stdClass Object
                (
                )

        )

)

Any help or tips would be greatly appreciated! Thanks!

Answer 1

Figured this out myself and decided to share:

$info = new StdClass;
$info->Origin = "BRL";
$info->Destination = "ORD";
$info->UseAirportsNotMetroGroups = false;
$info->UseAirportsNotMetroGroupsAsRule = false;
$info->UseAirportsNotMetroGroupsForForm = false;
$info->UseAirportsNotMetroGroupsForTo = false;
$info->DateOfDeparture = "2016-11-20";
$info->FareTypeCategory = 1;
$info->FareClass = null;
$info->FareBasisCode = null;
$info->Cabin = null;
$info->LFID = -214;
$info->OperatingCarrierCode = null;
$info->MarketingCarrierCode = null;
$info->NumberOfDaysBefore = 0;
$info->NumberOfDaysAfter = 0;
$info->LanguageCode = "en";
$info->TicketPackageID = 1;
$info->FareQuoteRequestInfos->FareQuoteRequestInfo[] = array(
    'PassengerTypeID' => 1,
    'TotalSeatsRequired' => 1
);
$info->FareQuoteRequestInfos->FareQuoteRequestInfo[] = array(
    'PassengerTypeID' => 5,
    'TotalSeatsRequired' => 1
);
$info->FareQuoteRequestInfos->FareQuoteRequestInfo[] = array(
    'PassengerTypeID' => 6,
    'TotalSeatsRequired' => 1
);

$detail = new StdClass;
$detail->FareQuoteDetail = $info;

$data->CurrencyOfFareQuote = "USD";
$data->CorporationID = -214;
$data->FareFilterMethod = "NoCombinabilityRoundtripLowestFarePerFareType";
$data->FareGroupMethod = "WebFareTypes";
$data->InventoryFilterMethod = "Available";
$data->ClientIPAddress = "?"; // Optional
$data->HistoricUserName = "?"; // Optional
$data->PromotionalCode = null;
$data->IataNumberOfRequestor = null;
$data->FareQuoteDetails = $detail;

$quote = $pricing->RetrieveFareQuote(array("RetrieveFareQuoteRequest" => $data));

print_r($quote);

I moved the FareQuoteDetail into a separate class object and then added each FareQuoteRequestInfo as an array, which let me keep the same naming structure.
