如何查看PHP SOAP Client Class生成的实际XML？

Question

Consider this example SOAP Client script:

$SOAP = new SoapClient($WDSL); // Create a SOAP Client from a WSDL

// Build an array of data to send in the request.
$Data = array('Something'=>'Some String','SomeNumber'=>22); 

$Response = $SOAP->DoRemoteFunction($Data); // Send the request.

On the last line, PHP takes the arguments from the array you specified, and, using the WSDL, builds the XML request to send, then sends it.

How can I get PHP to show me the actual XML it's built?

I'm troubleshooting an application and need to see the actual XML of the request.

Use getLastRequest. It returns the XML sent in the last SOAP request.

echo "REQUEST:
" . $SOAP->__getLastRequest() . "
";

And remember, this method works only if the SoapClient object was created with the trace option set to TRUE. Therefore, when creating the object, use this code:

$SOAP = new SoapClient($WDSL, array('trace' => 1));
