Basic Sessions?

[phpforfun]

Pretty basic, but for some reason im stuck. I cant get sessions to run.. I dont think. Or maybe I have a problem getting the set information.

Look at this..

http://analyzethathost.com/session.php

the EXACT code for that is this.

PHP Code:

<?
session_start();
$username = $_SESSION['username'];
if(isset($username)){
    Echo $username;
} Else {
    if(isset($_GET['do'])){
         session_register("username", JohnDoe);
        Echo 'session started! <a href="?">Click here to go home and view the name your session was started with</a>';
    } Else {
        Echo '<a href="?do=yes">click here to start session</a>';
    }
}
?>

I was told that is the correct code, and its the code I pretty much cut and pasted from the other music site I had a while back..

any ideas? Does it work for you guys?

PHP: session_register - Manual

If you want your script to work regardless of register_globals, you need to instead use the $_SESSION array as $_SESSION entries are automatically registered. If your script uses session_register(), it will not work in environments where the PHP directive register_globals is disabled.
