Answer 1

A very basic example of a SOAP webservice:

The server part (server.php):

<?php
function getRot13($pInput) {
    $rot = str_rot13($pInput);
    return($rot);
}

function getMirror($pInput) {
    $mirror = strrev($pInput);
    return $mirror;
}

ini_set("soap.wsdl_cache_enabled", "0");

$server = new SoapServer('scramble.wsdl');

$server->addFunction("getRot13");
$server->addFunction("getMirror");

$server->handle();

The client part (client.php):

<?php
// turn off the WSDL cache
ini_set("soap.wsdl_cache_enabled", "0");

$client = new SoapClient("http://localhost/test/scramble.wsdl");

$origtext = "mississipi";

print("The original text : $origtext\n");

$mirror = $client->getMirror($origtext);
print("The mirrored text : $mirror\n");

$scramble = $client->getRot13($mirror);
print("The scrambled text : $scramble\n");

And finally the WSDL file (scramble.wsdl):

<?xml version ='1.0' encoding ='UTF-8' ?>
<definitions name='Scramble' 
  targetNamespace='http://localhost/test/scramble.wdsl' 
  xmlns:tns='http://localhost/test/scramble.wdsl' 
  xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/' 
  xmlns='http://schemas.xmlsoap.org/wsdl/'&gt; 

<message name='getRot13Request'> 
  <part name='symbol' type='xsd:string'/> 
</message> 
<message name='getRot13Response'> 
  <part name='Result' type='xsd:string'/> 
</message> 
<message name='getMirrorRequest'> 
  <part name='symbol' type='xsd:string'/> 
</message> 
<message name='getMirrorResponse'> 
  <part name='Result' type='xsd:string'/> 
</message> 

<portType name='ScramblePortType'> 
  <operation name='getRot13'>
    <input message='tns:getRot13Request'/> 
    <output message='tns:getRot13Response'/>   
  </operation>
  <operation name='getMirror'>
    <input message='tns:getMirrorRequest'/> 
    <output message='tns:getMirrorResponse'/>   
  </operation>    
</portType> 

<binding name='ScrambleBinding' type='tns:ScramblePortType'> 
  <soap:binding style='rpc' 
    transport='http://schemas.xmlsoap.org/soap/http'/&gt; 
  <operation name='getRot13'> 
    <soap:operation soapAction='urn:localhost-scramble#getRot13'/> 
    <input> 
      <soap:body use='encoded' namespace='urn:localhost-scramble' 
        encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/&gt; 
    </input> 
    <output> 
      <soap:body use='encoded' namespace='urn:localhost-scramble' 
        encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/&gt; 
    </output> 
  </operation>
  <operation name='getMirror'> 
    <soap:operation soapAction='urn:localhost-scramble#getMirror'/> 
    <input> 
      <soap:body use='encoded' namespace='urn:localhost-scramble' 
        encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/&gt; 
    </input> 
    <output> 
      <soap:body use='encoded' namespace='urn:localhost-scramble' 
        encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/&gt; 
    </output> 
  </operation>       
</binding> 

<service name='ScrambleService'> 
  <port name='ScramblePort' binding='ScrambleBinding'> 
    <soap:address location='http://localhost/test/server.php'/&gt; 
  </port> 
</service>
</definitions>

This example assumes you put these three files in a directory that is accessible from http://localhost/test and if you use another location, find and replace with the correct URL.

Also it requires the SOAP PHP extension to be installed. Good luck!
