Description: ------------ I'm trying to implement a webservice with SoapServer and a WSDL description. The execution on the server works fine, parameters are passed and used correctly. However, the returned answer by SoapServer begin with a cr/lf/blank in front of "<?xml..." leading to a "looks like we got no XML document" when called by SoapClient (by the way it's the same when I call it from a VC++/ATL client, so SoapClient seems to have no problem at all). I traced the network traffic and found the CR/LF/blank (ASCII 32) as first character in the HTTP-body. Reproduce code: --------------- // SoapServer: // function get_aktie_detail is defined $server = new SoapServer("soap.wsdl"); $server->addFunction('get_aktie_detail'); ini_set("soap.wsdl_cache_enabled", "0"); $data = $HTTP_RAW_POST_DATA; $server->handle($data); // server-side execution works fine! // SoapClient: $client = new SoapClient("http://192.168.1.200/joomla/components/com_parse/soap.wsdl"); $id = 33; $objectresult = $client->get_aktie_detail($id); // WSDL: <?xml version='1.0' encoding='UTF-8'?> <!-- WSDL file generated by Zend Studio. --> <definitions name="frognetService" targetNamespace="urn:frognetService" xmlns:typens="urn:frognetService" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/"> <message name="get_aktie_detail"> <part name="id" type="xsd:int"/> </message> <message name="get_aktie_detailResponse"> <part name="get_aktie_detailReturn" type="xsd:int"/> </message> <portType name="HTMLPageServicePortType"> <operation name="get_aktie_detail"> <input message="typens:get_aktie_detail"/> <output message="typens:get_aktie_detailResponse"/> </operation> </portType> <binding name="HTMLPageServiceBinding" type="typens:HTMLPageServicePortType"> <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="get_aktie_detail"> <soap:operation soapAction="urn:HTMLPageServiceAction"/> <input> <soap:body namespace="urn:frognetService" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </input> <output> <soap:body namespace="urn:frognetService" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </output> </operation> </binding> <service name="frognetServiceService"> <port name="HTMLPageServicePort" binding="typens:HTMLPageServiceBinding"> <soap:address location="http://192.168.1.200/joomla/components/com_parse/soap.php"/> </port> </service> </definitions> Expected result: ---------------- As a result, $objectresult is expected to contain the return value of the webservice.
