This class is useful when dealing with the "anyType" type (generic object reference): it lets you specify the xsd type to provide "late binding" type information.



Here's a really simple example: I have a .NET service that can take a string, a date, and integer, or other types, so I use the .NET "object" type. Here's an example of such a service--this one just tells me what type I passed in. (It's nice to use when checking to see if PHP passed in the type information the way .NET expects it.)



//inside a service.asmx.cs file...

[WebMethod]

public string WhatTypeIsThis(object ObjectParameter)

{

   return "You passed in a " + ObjectParameter.GetType().Name 

     + ": " + ObjectParamter.ToString();

}



To call this service with a string from PHP, I used this code:

<?php

//set up the service client using WSDL

$client = new SoapClient("http://localhost/folder/service.asmx?WSDL");



//This is the variable that will be typed as an XSD string

$typedVar = new SoapVar("mystring", XSD_STRING, "string", "http://www.w3.org/2001/XMLSchema");

//This is the wrapper object for incoming parameters

$wrapper->ObjectParameter = $typedVar;

//This is the named parameter object that will be passed in to the service

$params = new SoapParam($wrapper, "WhatTypeIsThis");



//call the service with the string

$result = $client->WhatTypeIsThis($params);

//show the result

echo $result->WhatTypeIsThisResult;

?>



The output from this should be:

"You passed in a String: mystring"



The SOAP message that is passed in looks like this:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns1="http://tempuri.org/">

    <SOAP-ENV:Body>

        <ns1:WhatTypeIsThis>

            <ns1:ObjectParameter xsi:type="xsd:string">mystring</ns1:ObjectParameter>

        </ns1:WhatTypeIsThis>

    </SOAP-ENV:Body>

</SOAP-ENV:Envelope>



It's that xsi:type="xsd:string" that gives .NET the heads up that though the ObjectParameter is being passed in as an object, it is also a string. 



When trying other types, it's helpful to see exactly what is being sent to the service--to see the SOAP messages like the one above, use the trace option when making your SOAP client and then call the $client->__getLastRequest() function. (See soap_soapclient_getlastrequest)  You may need to use try/catch constructs if you're generating errors.



Another helpful function is var_dump($client->__getTypes())--it shows how PHP parsed the WSDL file to create types to pass back and forth.
