The best way is to destroy your session at the end of the php code using session_destroy()

It depends on your application, If you want to destroy all php sessions use session_destroy(). If you want to destroy a particular session use unset($_SESSION['name_here']).

Of course there are times when you may not want to destroy all session variables as they are not only used for logins and logouts. For that pupose you'll use unset($_SESSION['name_here`]).

I use this piece of code to log somebody out:

<?php
    $_SESSION = array();
    session_destroy();
    unset($_SESSION);
    header('Location: '.ROOT_HREF.');
    die();
?>
