mau tanya tentang koding ini..
kenapa ya "$class" ga bisa di echo..outputnya selalu kosong..

<?php

 function statuscheck($serverip, $port) {

 $sockres = @fsockopen($serverip, $port, $errno, $errstr, 1);

 if (!$sockres) {

 $class = "label label-important";

 return "<i class='icon-download icon-white'></i> Offline";

 } else {

 @fclose($sockres);

 $class = "label label-success";

 return "<i class='icon-upload icon-white'></i> Online";

 }

 }

 $st_login = statuscheck($login_ip,$login_port);

 $st_non = statuscheck($ch1_ip,$ch1_port);

 $st_pk = statuscheck($ch2_ip,$ch2_port);

 

?>

 <li><span class="<? echo $class ?>">Login : <? echo $st_login ?></span></li>

 <li><span class="<? echo $class ?>">CH 1 �: <? echo $st_non ?></span></li>

 <li><span class="<? echo $class ?>">CH 2 �: <? echo $st_pk ?></span></li>
