I need to consume a web service https://www.example.com/example.svc?wsdl in PHP. For this purpose, I am using PHP SOAP client. The code snippet like below:

$client = new SoapClient("https://www.example.com/example.svc?wsdl", array('soap_version' => SOAP_1_2, 'location'=>'https://www.example.com/example.svc', 'login'=> '#####', 'password'=> '#######', 'exceptions'=>true, 'trace'=>1, 'cache_wsdl'=>WSDL_CACHE_NONE, 'encoding'=>'UTF-8', 'connection_timeout' => 500, 'keep_alive' =>false)); $client->__call('getProductList',array());

However, when I run this its through following error:

Warning: SoapClient::__doRequest(): SSL: The operation completed successfully. in E:\location\test1.php on line 37 Fatal error: Uncaught SoapFault exception: [HTTP] Error Fetching http headers in E:\location\test1:37 Stack trace: #0 [internal function]: SoapClient->__doRequest('<?xml version="...', 'https://travius...', 'Travius/ITraviu...', 2, 0) #1 E:\location\test1(37): SoapClient->__call('getProductList', Array) #2 {main} thrown in E:\location\test1.php on line 37

I am struggling several days to solve the error but can't figure out. I tried the different solution in stack overflow like 'keep_alive' =>false , connection_timeout but nothing works.

I also try with php nusoap library. its request and response are like following:

Error HTTP Error: Unsupported HTTP response status 400 Bad Request (soapclient->response has contents of the response) Request POST /#####.svc?wsdl HTTP/1.0 Host: #####.#####.eu User-Agent: NuSOAP/0.9.5 (1.123) Content-Type: application/soap+xml;charset=UTF-8; charset=UTF-8 SOAPAction: "" Authorization: Basic RGVtb2FwaTpEdXE1dmRWdA== Content-Length: 529 <?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><GetProduct><parameters><intProductID xsi:type="xsd:int">1266</intProductID><lang xsi:type="xsd:string">CN</lang></parameters></GetProduct></SOAP-ENV:Body></SOAP-ENV:Envelope> Response HTTP/1.1 400 Bad Request Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Mon, 02 Oct 2017 16:03:04 GMT Content-Length: 0

Please note that this web service works fine in .Net application. Any help highly appreciated. Thanks in advance.
