Fatal error: Uncaught SoapFault exception: [HTTP] Error Fetching http headers

Question

I'm trying to output "Hello World" using XML but I'm getting the following exception in my php page:

Fatal error: Uncaught SoapFault exception: [HTTP] Error Fetching http headers in C:\wamp\www\Web_Service\SampleXML\index.php:4 Stack trace:

    $client = new SoapClient('service.wsdl');
    $response = $client->getHelloWorld(); 
    echo $response;

soap-server.php

<?php

    function getHelloWorld() {
        return "Hello World";
    }

    ini_set("soap.wsdl_cache_enabled", "0");

    $server = new SoapServer('service.wsdl');
    $server->addFunction("getHelloWorld");    
    $server->handle();

?>

Did I miss something in the code?

Answer 1

try to set this line,

ini_set("default_socket_timeout", 200);

or put this in php.ini

 default_socket_timeout = 200
