<pre lang="xml"><?php
  require_once("lib/nusoap.php");

      putenv("NLS_LANG=American_America.ZHT16BIG5");
      $client = new nusoap_client('https://140.130.11.55/ws/LibService_test.php?wsdl',true);

  $client->setCredentials("user","password");

  $parameters=array('2011/03/01');
  $str=$client->call('GetStaffListCount',$parameters);    

if (!$err=$client->getError()) {
      //echo " return:",htmlentities($str,ENT_QUOTES);  //the optional second quote_style  parameter lets you define what will be done with 'single' and "double" quotes. It takes on one of three constants with the default being ENT_COMPAT:  ,ENT_QUOTES      Will convert both double and single quotes.
  } else {
      echo " error :",htmlentities($err,ENT_QUOTES);
