Description:
------------
I am trying to create a standalone SOAP server with PHP. So far the results are close to NULL, because the SoapServer::handle() functions throws an error complaining about headers being sent already.

It would be truly appreciated if support for STANDALONE SOAP service gets implemented. All that needs to be done is to implement another handle*() function, which, instead of using header() function (or PHP internal equivalent) to send HTTP headers, returns every part of response as a string.

Sample code:
(...here we create the listening socket etc...)
$clientSocket = socket_accept($listenSocket);
$soapRequest = socket_read($clientSocket, ...);
$soapResponse = SoapServer::handleToString($soapRequest);
socket_write($clientSocket, $soapResponse);
socket_close($clientSocket);
