HelloServerWsdl2.php - SOAP 1.1/1.2 Server in WSDL Mode

This section describes a tutorial example of a complete SOAP application with both server and client programs that supports both SOAP 1.1 and SOAP 1.2 with a single WSDL file.

You can actually create a single server application to support both SOAP 1.1 and SOAP 1.2 in WSDL mode. Here is the same hello server modified to work in WSDL mode for SOAP 1.1/SOAP 1.2, HelloServerWdsl2.php:

<?php # HelloServerWsdl2.php
# Copyright (c) 2007-2018 HerongYang.com, All Rights Reserved.
#
function hello($someone) { 
   return "Hello " . $someone . "! - With WSDL/SOAP 1.1/1.2";
} 
   ini_set("soap.wsdl_cache_enabled", "0"); 
   $server = new SoapServer("http://localhost/Hello2.wsdl");
   $server->addFunction("hello"); 
   $server->handle(); 
?>

Nothing special in the program. The server object is now created with the location of the WSDL document. The SOAP version will be determined dynamically based on the SOAP request message.

Here is the WSDL document, Hello2.wsdl, which supports both SOAP 1.1 and SOAP 1.2:

To install HelloServerWsdl2.php to my Apache server, copy these two files to the Apache document directory:

C:\herong>copy HelloServerWsdl2.php \local\apache\htdocs
C:\herong>copy Hello2.wsdl \local\apache\htdocs

Of course, we need to modify our hello client program as, HelloClientWsdl2.php:

<?php # HelloClientWsdl2.php
# Copyright (c) 2018 HerongYang.com, All Rights Reserved.
#
   $soap_version = '1.1';
   if (count($argv) > 1) $soap_version = $argv[1];
   
   if ($soap_version == '1.1') {
      $client = new SoapClient("http://localhost/Hello2.wsdl",
         array('soap_version' => SOAP_1_1, 'trace' => 1 ));
   } else if ($soap_version == '1.2') {
      $client = new SoapClient("http://localhost/Hello2.wsdl",
         array('soap_version' => SOAP_1_2, 'trace' => 1 ));
   } else {
      $client = new SoapClient("http://localhost/Hello2.wsdl",
         array('trace' => 1 ));
   }

   echo("\nDumping client object functions:\n");
   var_dump($client->__getFunctions());

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

#   $return = $client->hello("world");
#   echo("\nReturning value: ".$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());
?>

Now run "HelloClientWsdl2.php 1.1" to test the SOAP 1.1 version:

C:\herong>php HelloClientWsdl2.php 1.1

...
Dumping response:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:ns1="urn:myOutputNamespace"
 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:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
 <SOAP-ENV:Body>
  <ns1:helloResponse>
   <resParam
    xsi:type="xsd:string">Hello world! - With WSDL/SOAP 1.1/1.2</resParam>
  </ns1:helloResponse>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Good. I am getting the response back in SOAP 1.1 format as expected.

Then run "HelloClientWsdl2.php 1.2" to test the SOAP 1.2 version:

C:\herong>php HelloClientWsdl2.php 1.2

Dumping response:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope
 xmlns:env="http://www.w3.org/2003/05/soap-envelope"
 xmlns:ns1="urn:myOutputNamespace"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:enc="http://www.w3.org/2003/05/soap-encoding">
 <env:Body xmlns:rpc="http://www.w3.org/2003/05/soap-rpc">
  <ns1:helloResponse
   env:encodingStyle="http://www.w3.org/2003/05/soap-encoding">
   <rpc:result>resParam</rpc:result>
   <resParam
    xsi:type="xsd:string">Hello world! - With WSDL/SOAP 1.1/1.2</resParam>
  </ns1:helloResponse>
 </env:Body>
</env:Envelope>

Cool. I am getting the response back in SOAP 1.2 format as expected.
