script not working

[nomad3212]

I am trying to execute this code. can anyone tell me what are the things/values to get this code up and running ?? This code is to implement TripAdvisor API.

 

The code is :

 

$client = new nusoap_client('http://demo02.tripadvisor.com/ContentService', true);

$err = $client->getError();

  if ($err) {

    echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';

    echo '<h2>Debug</h2><pre>' . htmlspecialchars($client->getDebug(), ENT_QUOTES) . '</pre>';

    exit();

  }

  $param = '<con:in0><api:clientLoginID>3CFC3B05146B40048B0C105A6CB9748F</api:clientLoginID><api:listId>16794</api:listId></con:in0>';

$result = $client->call('getTop10List', $param, 'con:getTop10List');

$client->call('getTop10List', $param, 'con:getTop10List');

 

if ($client->fault) {

  $output .= '<h2>Fault</h2><pre>'; print_r($result); echo '</pre>';

} else {

  $err = $client->getError();

  if ($err) {

    $output .= '<h2>Error</h2><pre>' . $err . '</pre>';

  } else {

    $output .= '<h2>Result</h2><pre>'; print_r($result); echo '</pre>';

  }

}

$output .= '<h2>Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';

$output .= '<h2>Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';

$output .= '<h2>Debug</h2><pre>' . htmlspecialchars($client->getDebug(), ENT_QUOTES) . '</pre>';
