Again Complex Types in Response

Hello * I've buildt a webservice with PEAR::SOAP using WSDL... and try to have returned an assoziative ARRAY as response (like $result["user"]["anything"]). without using assoziative arrays within the server function it works fine. case: I return array(245,49); and I get an Array $result[0]=245 [1]=49 in PHP. well. case: I return an array("user"=>246,"country"0>49) it returns a stdClass Object in PHP. I tried to figure out what the matter could be. I guessed it's the __dispatch_map or maybe a bug? , but I'm stuck with no idea where to start searching for help. so, is there anyone with a hint.. regards & thx ;]
