You can use session object to store those values.

Storing value to session.
session_start();
$_SESSION['user_id'] = $userid; //storing the $userid value to session
$_SESSION['UserName'] = $username; //storing the $username value to session

To retrieve (sample ONLY)
====================
session_start();
if($_SESSION['user_id']) //check first in case..
$ID = $_SESSION['user_id']) //set it to variable $ID

Comment on 'neele':

If I use 'session_start()' , it complains about '....cookie already sent...' and '..cache limit already sent'...'
If I don't use 'session_start()', it complains about '...undefined variable _SESSION...'.

check in your php.ini :
session.auto_start = 1 //set to 1 so it auto-start the session.
session.save_path = C:\php\sessiondata //set the path for storing the session..data
session.use_trans_sid = 1

Try checking the setting..n see whether it works..

AND do place session_start(); at the very beginning of your code. If u r having other code..
in between..

e.g.
<?php
session_start();
....
....

?>


hope it helps
