∟PHP SOAP Extension - XML Document Based Web Services

This section provides a tutorial example on how to write a PHP program to call an XML document based Web service with SOAP 1.2 binding using the SoapClient class. 'soap_version' => SOAP_1_2 is used for SOAP 1.2.

To test XML document based Web services, I used my Reservation service. Here is my example PHP program, Reservation_SOAP12_Client.php:

<?php 
# Reservation_SOAP12_Client.php
# Copyright (c) 2009 by Dr. Herong Yang, herongyang.com
# All rights reserved

#- Loading the WSDL document
   $server = "http://www.herongyang.com/Service/";
   $wsdl = $server . "Reservation_WSDL_11_SOAP_12_Document.wsdl";
   $client = new SoapClient($wsdl,
      array('trace' => TRUE, 'soap_version' => SOAP_1_2));

#- Creating the XML document
   $xml = <<<EOT
<hy:Reservation xmlns:hy="http://www.herongyang.com/Service/">
  <Member>Herong Yang</Member>
  <ItemList>
    <Item>Java Web Services</Item>
    <Item>SOAP Programming</Item>
  </ItemList>
</hy:Reservation>
EOT;
   $body = new SoapVar($xml,XSD_ANYXML);

#- Calling the service method
   $result = $client->Reservation($body);

#- Showing the request and reponse
   print $client->__getLastRequest()."\n";
   print $client->__getLastResponse()."\n";
?>

Here is the result of this tutorial program:

<env:Envelope
  xmlns:env="http://www.w3.org/2003/05/soap-envelope"
  xmlns:ns1="http://www.herongyang.com/Service/">
  <env:Body>
<hy:Reservation xmlns:hy="http://www.herongyang.com/Service/">
  <Member>Herong Yang</Member>
  <ItemList>
    <Item>Java Web Services</Item>
    <Item>SOAP Programming</Item>
  </ItemList>
</hy:Reservation>
  </env:Body>
</env:Envelope>

<soapenv:Envelope
  xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:hy="http://www.herongyang.com/Service/">
  <soapenv:Header/>
  <soapenv:Body>
    <hy:ReservationResponse>
      <Number>20080808</Number>
      <Status>Wait</Status>
    </hy:ReservationResponse>
  </soapenv:Body>
</soapenv:Envelope>

This proves that SOAP Extension in PHP 5.3.1 does support XML document based Web services defined in WSDL 1.1 with SOAP 1.2 binding.
