PHP SOAP Extension - Server Applications

Part:   1  2  3  4 

(Continued from previous part...)

To test my server application, I wrote this client application, HelloClient.php:

<?php # HelloClient.php
# Copyright (c) 2005 by Dr. Herong Yang
#
   $client = new SoapClient(null, array(
      'location' => "http://localhost/HelloServer.php",
      'uri'      => "urn://www.herong.home/req",
      'trace'    => 1 ));

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

Check your IIS server to make sure it is running. Then run HelloClient.php. You will get:

Returning value of __soapCall() call: Hello world!

Dumping request headers:
POST /HelloServer.php HTTP/1.1
Host: localhost
Connection: Keep-Alive
User-Agent: PHP SOAP 0.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "urn://www.herong.home/req#hello"
Content-Length: 499

Dumping request:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
 xmlns:ns1="urn://www.herong.home/req" 
 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:hello>
  <param0 xsi:type="xsd:string">world</param0>
 </ns1:hello></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Dumping response headers:
HTTP/1.1 200 OK
Server: Microsoft-IIS/5.1
Connection: close
Content-Type: text/xml; charset=utf-8
X-Powered-By: PHP/5.0.4
Content-Length: 522

Dumping response:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
 xmlns:ns1="urn://www.herong.home/res" 
 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>
  <return xsi:type="xsd:string">Hello world!</return>
 </ns1:helloResponse></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Very exciting, right? Both server and client work nicely.

If you are interested in how the execution was carried out on the server, I have a simplified execution flow diagram on the server side:

                 IIS      PHP (SOAP Extension)      HelloServer.php
    HTTP request  | 
   -------------->| 
    SOAP message  | 
                  |  CGI   |      PHP CGI API        
                  |------->|------------------------>| 
                                                     | addFunction()
                                                     |
                                SOAP Extension API   | handle()
                           |<------------------------|
                           |
                           |    SOAP Extension API
                           |------------------------>|
                                SOAP Extension API   | hello()
                           |<------------------------|
                     CGI   |
                  |<-------|
    HTTP response | 
   <--------------| 
    SOAP message  | 

HelloServer12.php - SOAP 1.2 Server Application

So far, we have tried only with SOAP 1.1. Can we do some tests with SOAP 1.2? Sure. Here is my hello server modified for SOAP 1.2, HelloServer12.php:

<?php # HelloServer12.php
# Copyright (c) 2005 by Dr. Herong Yang
#
function hello($someone) { 
   return "Hello " . $someone . "! - SOAP 1.2";
} 
   $server = new SoapServer(null, array(
      'uri' => "urn://www.herong.home/res",
      'soap_version' => SOAP_1_2));
   $server->addFunction("hello"); 
   $server->handle(); 
?>

Here is my hello client modified for SOAP 1.2, HelloClient12.php:

<?php # HelloClient12.php
# Copyright (c) 2005 by Dr. Herong Yang
#
   $client = new SoapClient(null, array(
      'location' => "http://localhost/HelloServer12.php",
      'uri'      => "urn://www.herong.home/req",
      'soap_version' => SOAP_1_2,
      'trace'    => 1 ));

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