Configuring and Testing SOAP Extension

This section provides a tutorial example on how to configure and test SOAP Extension with a WSDL 2.0 document. It fails with an error.

Once PHP is installed, I need to turn on the SOAP Extension with these steps:

1. If \local\php\php.ini does not exist, create it by copying the file \local\php.ini-production.

2. Edit \local\php\php.ini to set these configuration settings:

...
extension_dir = "C:\local\php\ext"
...
extension=php_soap.dll
...

3. Creating a testing PHP program, SOAP_Hello.php:

<?php 
#- WDSL_20_Hello.php
#- Copyright (c) 2009 HerongYang.com, All Rights Reserved.

  $client = new SoapClient(
      "file:///C:/herong/Hello_WSDL_20_SOAP.wsdl");
   echo $client->Hello("Hello from client.");
?>

4. Run the test program:

C:\herong>\local\php\php WSDL_20_Hello.php

PHP Fatal error:  SOAP-ERROR: 
   Parsing WSDL: Couldn't find <definitions> 
   in 'file:///C:/herong/Hello_WSDL_20_SOAP.wsdl' 
   in C:\herong\WSDL_20_Hello.php on line 6
   
Stack trace:
#0 C:\herong\WSDL_20_Hello.php(6): 
   SoapClient->SoapClient('file:///C:/hero...')
#1 {main}
   thrown in C:\herong\WSDL_20_Hello.php on line 6
...

As you can see, PHP SOAP Extension fails to parse the WSDL 2.0 "description" element. It is expecting the WSDL 1.1 "definitions" element.

Conclusion: PHP SOAP Extension does not support WSDL 2.0.

See other tutorials in this book on how to use PHP SOAP Extension to test WSDL 1.1 documents.
