PHP调用WebService，求大神帮忙看下~

$wsdl="http://pica.chalwin.com/service/JsAccessWebService.asmx?wsdl";

$client = new SoapClient($wsdl);

$param = array('NodeId'=>'1','outCount'=>'10');

$ret = $client->LatestNews($param);

if($ret->return){

  print_r($ret->return);

}else{

  echo 'no user';

}

?>

简单的调用Webservice，这是什么错呢？求大神指导~

foreach($ret->LatestNewsResult->InheritanceNews as $item) {

  foreach($item as $k=>$v) {

    echo "$k : $v\n";

  }

}
