Answer 1

The unset() function frees a specific session variable so you would use it like this

unset($_SESSION['name']);

You can also use the session_destroy function to destroy all the session variables like this

session_destroy();

Answer 2

session_unset();
?>

will remove all session variables - if you want to completely destroy the session (as if they had closed their browser), use:

session_destroy();
?>

Direct your link 'Sign Out' to something like http://djabid.com/logout.php

And put something like the following in the logout.php file
session_destroy();
echo 'You've been successfully logged out';
?>

There are tons of ways to do this, depending on what you want the final result to be and how your code is set up thus far.
