∟Call WSDL Operation with SoapClient::__doRequest()

This section provides a tutorial example on how to call an operation defined in a WSDL document using the __doRequest(request,...) function.

Instead of using the RPC style, we can also call a Web service in XML style by using the SoapClient::__doRequest() function:

Identify the URL of the Web service location.
Build the SOAP request XML based given samples or documentation.
Create a SoapClient object with "null" as the WSDL URL, empty string for "uri", and empty string for "location".
Call the __doRequest() function on the SoapClient object with the request XML string as the first argument.
Provide the Web service URL as the second argument.
Dump the response XML returned from the call.

Here a good example of a client program, NumberConversionDoRequest.php, on how to call a Web service with the SoapClient::__doRequest() function. The NumberConversion Web service and its WSDL document are provided by dataaccess.com.

<?php 
# NumberConversionDoRequest.php
# Copyright (c) 2007 HerongYang.com. All Rights Reserved.
#
   $client = new SoapClient(null, array('uri'=>'', 'location'=>''));
   
   $request = <<<EOT
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:ns1="http://www.dataaccess.com/webservicesserver/">
 <SOAP-ENV:Body>
  <ns1:NumberToWords>
   <ns1:ubiNum>303</ns1:ubiNum>
  </ns1:NumberToWords>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
EOT;
   $url = 
      "https://www.dataaccess.com/webservicesserver/numberconversion.wso";
   $response = $client->__doRequest($request,$url,"",SOAP_1_1);

   echo("Request:\n");
   var_dump($request);
   echo("Response:\n");
   var_dump($response);
?>

When running it, I am getting:

string(318) "<?xml version="1.0" encoding="UTF-8"?>
