`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 $client->__getLastRequest() function. (See http://www.php.net/soap_soapclient_getlastrequest) You may need to use try/catch constructs if you're generating errors.
Another helpful function is var_dump($client->__getTypes())--it shows how PHP parsed the WSDL file to create types to pass back and forth.`
