Php-soap Related Problem

I am trying to develop a web service using WSDL, SOAP and PHP.  I did a sample code and it seems to run well but the only problem is that it is giving me the following error messages:

Warning: SoapClient::SoapClient(http://127.0.0.1/tutorial/inventory.wsdl) [soapclient.soapclient]: failed to open stream: HTTP request failed! in C:\wamp\www\tutorial\client-test.php on line 3

Warning: SoapClient::SoapClient() [soapclient.soapclient]: I/O warning : failed to load external entity "http://127.0.0.1/tutorial/inventory.wsdl" in C:\wamp\www\tutorial\client-test.php on line 3

Fatal error: Maximum execution time of 60 seconds exceeded in C:\wamp\www\tutorial\client-test.php on line 6

Any help will be greatly appreciated

client-test.php
<?php
    ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
    $client = new SoapClient("http://127.0.0.1/tutorial/inventory.wsdl");
    $return = $client->getItemCount('12345');
    print_r($return);
?>

$server = new SoapServer("c:/wamp/www/tutorial/inventory.wsdl");
$server->addFunction("getItemCount");
$server->handle();
