xml - Passing a PHP array in a SOAP call

Question

So I am trying to include the following XML in my SOAP request:

<Responses>
    <Response>
        <QuestionAnswerID>someint</QuestionAnswerID>
        <QuestionID>someint</QuestionID>
    </Response>
    <Response>
        <QuestionAnswerID>someint</QuestionAnswerID>
        <QuestionID>someint</QuestionID>
    </Response>
</Responses>

I looked at this posting, which is vaguely on the same topic, but it produces output like so:

object(stdClass)#1 (1) {
    ["Responses"]=>
    object(stdClass)#2 (1) {
        ["Response"]=>
        array(2) {
            [0]=>
            object(stdClass)#3 (2) {
                ["QuestionAnswerID"]=>
                int(someint)
                ["QuestionID"]=>
                int(someint)
            }
            [1]=>
            object(stdClass)#4 (2) {
                ["QuestionAnswerID"]=>
                int(someint)
                ["SurveyQuestionID"]=>
                int(someint)
            }
        }
    }
}

The problem with that is that the arrays now have indices, which the web service I'm calling appears to not like. Any way I can generate something like the above XML?

TIA.

It's hard to test this without a SOAP server with your WSDL to go against. You should be able to create associative arrays like so:

$responses = array();
$responses[] = array("QuestionAnswerID" => someint, "QuestionID" => someint);
$responses[] = array("QuestionAnswerID" => someint, "QuestionID" => someint);

$response = array("Response" => $responses);

$soapData = array("Responses" => $response);
