nusoap simple server

Please change your code to,

<?php//call libraryrequire_once('nusoap.php');$URL       = "www.test.com";$namespace = $URL . '?wsdl';//using soap_server to create server object$server    = new soap_server;$server->configureWSDL('hellotesting', $namespace);//register a function that works on server$server->register('hello');// create the functionfunction hello($name){    if (!$name) {        return new soap_fault('Client', '', 'Put your name!');    }    $result = "Hello, " . $name;    return $result;}// create HTTP listener$server->service($HTTP_RAW_POST_DATA);exit();?>

You didnt Define namespace..

Please see simple example here :-

The web browser is not calling the Web service - you could create a PHP client :

// Pull in the NuSOAP coderequire_once('lib/nusoap.php');// Create the client instance$client = new soapclient('your server url');// Call the SOAP method$result = $client->call('hello', array('name' => 'StackOverFlow'));// Display the resultprint_r($result);

This should display Hello, StackOverFlow

Update

To create a WSDL you need to add the following :

$server->configureWSDL(<webservicename>, <namespace>);

You can also use nusoap_client

<?php// Pull in the NuSOAP coderequire_once('lib/nusoap.php');// Create the client instance$client = new nusoap_client('your server url'); // using nosoap_client// Call the SOAP method$result = $client->call('hello', array('name' => 'Pingu'));// Display the resultprint_r($result)?>
