∟Calling an XML Document Based Web Service

This section provides a tutorial example on how to write a PHP program to call an XML document based Web service using the SoapClient class with the help of SoapVar($xml,XSD_ANYXML) constructor.

Now let's try to use XSD_ANYXML SoapVar objects to build more complex XML document based Web services. One example is my Reservation service, which is located at: https://www.herongyang.com/Service/ Reservation_WSDL_11_SOAP_11_Document.wsdl. The XML document in the request should look like this:

<soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:ser="https://www.herongyang.com/Service/">
  <soapenv:Header/>
  <soapenv:Body>
    <ser:Reservation>
      <Member>Herong Yang</hy:Member>
      <ItemList>
        <Item>Java Web Services</Item>
        <Item>SOAP Programming</Item>
      </ItemList>
    </ser:Reservation>
  </soapenv:Body>
</soapenv:Envelope>

Here is my example PHP program, Reservation_Client.php:

<?php
# Reservation_Client.php
# Copyright (c) 2007 HerongYang.com. All Rights Reserved.
#
#- Loading the WSDL document
   $server = "https://www.herongyang.com/Service/";
   $wsdl = $server . "Reservation_WSDL_11_SOAP_11_Document.wsdl";
   $client = new SoapClient($wsdl,
      array('trace' => TRUE));

#- Creating the XML document
   $xml = <<<EOT
<hy:Reservation xmlns:hy="https://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 response
   print $client->__getLastRequest()."\n";
   print $client->__getLastResponse()."\n";
?>

Here is the result of this tutorial program:

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

<soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:hy="https://www.herongyang.com/Service/">
  <soapenv:Header/>
  <soapenv:Body>
    <hy:ReservationResponse>
      <Number>20080808</Number>
      <Status>Wait</Status>
    </hy:ReservationResponse>
  </soapenv:Body>
</soapenv:Envelope>
