I am getting the following errors when trying to unset cookies:

Warning: Cannot modify header information - headers already sent by (output started at C:\wamp\www\staging\includes\functions.php:209) in C:\wamp\www\staging\logout.php on line 19

 

The code is as follows:

 

logout.php:

<?
   session_start();
   require('includes/functions.php');

   $pgval = (is_logged_in($user) ? 0 : 1);
   toppers('logout','');
?>
   <div id="content">
      <div id="flashcontent">
         <div class="eastc">
            <div id='spotlight'>
               <div id='featured'>
<?
   if($pgval == 1) {
      echo " <div class='x-tab' title='Message'>You are currently not logged in </div>";
   } else {

      unset($user);
      setcookie("user", false);
      $user = "";      

      echo " <div class='x-tab' title='Message'>You have been logged out, <br /> We look forward to your next visit! </div>";     
   }
?>
               </div>

      </div>
      <div id="copy">
      </div>
      <div id="banner">

<?
   footers();
?>

 

functions.php: (the lines that matters)

function toppers($pg,$user) {

What could be the problem, how can i make sure that the cookie gets destroyed so the application knows you are no longer logged in.

 

Thank you
