PHP调用WebService，求大神帮忙看下~

<br />
<?php<br />
$wsdl="http://pica.chalwin.com/service/JsAccessWebService.asmx?wsdl";<br />
$client = new SoapClient($wsdl);<br />
$param = array('NodeId'=>'1','outCount'=>'10');<br />
$ret = $client->LatestNews($param);<br />
if($ret->return){<br />
  print_r($ret->return);<br />
}else{<br />
  echo 'no user';<br />
}<br />
?><br />

简单的调用Webservice，这是什么错呢？求大神指导~

foreach($ret->LatestNewsResult->InheritanceNews as $item) {<br />
  foreach($item as $k=>$v) {<br />
    echo "$k : $v\n";<br />
  }<br />
}
