Using SOAP Extension in non-WDSL Mode

<< PHP SOAP Extension Client Programs

<< Herong's Tutorial Notes on Web Service and SOAP

This section describes a tutorial example on how to use PHP SOAP Extension client functions without WSDL.

I think we had enough fun with the WSDL mode. Let's try the non-WSDL mode now. Here is the third version of my getTemp SOAP client program, GetTempNonWsdl.php:

<?php # GetTempNonWsdl.php
# Copyright (c) 2005 by Dr. Herong Yang
#
   $zip = "123456";
   $client = new SoapClient(null, array(
      'location' => 
         "http://services.xmethods.net:80/soap/servlet/rpcrouter",
      'uri'      => "urn:xmethods-Temperature-Demo", 
      'trace'    => 1 ));

   echo("\nDumping client object:\n");
   var_dump($client);

   $return = $client->__soapCall("getTemp",array($zip));
   echo("\nReturning value of __soapCall() call: ".$return);

   echo("\nDumping request headers:\n" 
      .$client->__getLastRequestHeaders());

   echo("\nDumping request:\n".$client->__getLastRequest());

   echo("\nDumping response headers:\n"
      .$client->__getLastResponseHeaders());

   echo("\nDumping response:\n".$client->__getLastResponse());
?>

Here is output:

Dumping client object:
object(SoapClient)#1 (4) {
  ["uri"]=>
  string(29) "urn:xmethods-Temperature-Demo"
  ["location"]=>
  string(54) "http://services.xmethods.net:80/soap/servlet/rpcrouter"
  ["trace"]=>
  int(1)
  ["_soap_version"]=>
  int(1)
}

Returning value of __soapCall() call: 52

Dumping request headers:

Dumping request:

 <SOAP-ENV:Body><ns1:getTemp>
  <param0 xsi:type="xsd:string">123456</param0>
 </ns1:getTemp></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Dumping response headers:

Dumping response:
<?xml version='1.0' encoding='UTF-8'?>

 SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:float">52.0</return>
</ns1:getTempResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Output shows that:

• My GetTempNonWsdl.php works the same as the WSDL mode version.
• If you compare this output with the WSDL output, SOAP Extension generates the request headers with one difference: SOAPAction is not blank any more. It has the value of "urn:xmethods-Temperature-Demo#getTemp".
• SOAP Extension also generates the request message differently in non-WSDL mode. The input parameter is provided with an element named as "param0". In the WSDL version, that element is named as "zipcode".
