[RESOLVED] Global Variable

[Seitan]

How do I setup a global variable. I want my users to login to my site, and when they are logged in I want it to say "Welcome 'user_name' ". Could someone please help?

So far I have this

if (isset($SESSION['user_id']) AND
(substr($SERVER['PHP_SELF'], -10)
!= 'logout.php')) {
echo 'Hello ' . $u . '<a href ="../php/logout.php">Logout</a> | <a href ="../php/change_password.php">Change Password</a>';
} else {
echo '<a href ="../php/register.php">Register</a> | <a href ="../php/login.php">Login</a>
';
}

Is user_name in $SESSION ? If yes, simply use it, otherwise, insert it in $SESSION and then use it...
