If i try to get the vaule of a cookie inside the class, the command
HTTP_COOKIE_VARS return "" but if the same command run outside the class
return the correct value

Example

Archivo userctl.inc
<? 

class userctl {
  
    function userctl() {
      print $HTTP_COOKIE_VARS["ctl_user_cookie"];    // return ""
    }

?>

Archivo test.phpA
<?
   include("./userctl.inc");
   $user = new userctl;
   print $HTTP_COOKIE_VARS["ctl_user_cookie"];    //return "value"
?>
