Notice the URL used to construct <tt>SoapClient</tt> (a class provided by PHP SOAP extension).

In order for the WSDL generator to generate WSDL for a SOAP service, the provider class needs to follow certain syntax. In particular, for methods to be exposed as SOAP methods, a keyword <tt>@soapmethod</tt> must appear in the phpdoc comment of the method with the following lines specifying method parameters and return value:

Valid parameter and return types include: <tt>string</tt>, <tt>int</tt>, <tt>boolean</tt>, <tt>float</tt>, <tt>array</tt>, <tt>mixed</tt>, etc. You may also specify a class name as the type, which translates into a complex SOAP type. For example, for a complex type <tt>Contact</tt>
