Display users name when logged in

Hi all, I am wanting to display the name of the user that has logged in. I expect that I will need to use the session to do this. Currently my session uses the following $_SESSION['user_id'] = $user['id']; $_SESSION['logged_in'] = time(); I am not sure how to use the sessions user name id to get the name of the user from the database. Any help is appreciated. Thanks Adam

This is great - Thanks so much for your help. Means a lot.

I have been moving my code around and have caused myself a bit of an issue.

I am now getting the following.

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /Users/adamhewitt/Sites/registration/home.php:27) in /Users/adamhewitt/Sites/registration/header.php on line 5

<div>
<?php require_once 'header.php' ?>

<?php require_once 'footer.php' ?>


</div>

The first div is line 26

  if(!isset($_SESSION)) 
    { 
        session_start(); 
    }

Session start is line 5

Im not sure what I am doing wrong here
