it is showing only one user so i want to count all user online on user . so i count all user login session

i need help in this aspect if any person can thanks in advance

I don't think it will be as simple as using the $_SESSION property, especially since that is a per-user object (e.g., My $_SESSION instance will not have any information about anyone else's $_SESSION instance).

If you only want to know how many users are currently online, try

count(scandir(ini_get("session.save_path")));

This will give you the number of currently active sessions.

OR

you can use this way to find the count

   <?php
session_start();  
    function OnlineUsers() {
   $count = 0;  
       $handle = opendir(session_save_path());
   if    ($handle == false) return -1;  
       while (($file = readdir($handle)) != false) {
         if (ereg("^sess", $file)) $count++;
   }
   closedir($handle);  
       return $count;
}
?>

you can get the value using this way,

$usercount = OnlineUsers();

count all session of users on whole website
