         *
         * @return string
         */

        /**
         * Adds two numbers
         *
         * @param float $p1
         * @param float $p2
         * @return float

<?php
require_once('WSDLCreator.php');

$WSDLCreator = new WSDLCreator("myTestWsdl", "http://192.168.1.49/php2wsdl");
$WSDLCreator -> addFile("HelloWorldClass.php");
$WSDLCreator -> addURLToClass('HelloWorldClass',"http://192.168.1.49/php2wsdl/HelloWorldClass.php");
$WSDLCreator -> addURLToTypens("XMLCreator", "http://192.168.1.49/php2wsdl");
$WSDLCreator -> createWSDL();
$WSDLCreator -> printWSDL(true);
?>


SoapClient.PHP

<?php
    try
    {
        $client =   new SoapClient("http://192.168.1.49/php2wsdl/");
        echo "<pre>";
        echo $client    ->__soapCall('printHello',array());

    catch (Exception $e)
    {
        echo $e->getMessage()."<br><pre>";
    }
