logout.php:

setcookie("USERNAME" , '' , time()-50000, '/');
header("Location: index.php");
exit;

add a link to logout.php. logout.php should contain the code above.

setcookie("USERNAME" , '' , time()-50000, '/');

this destroys the cookie.

header("Location: index.php");
exit;

this redirects the user to index.php

I've removed the if statement cause i've realised it's not useful here

You might want to add an exit(); statement after the call to Header().

You are currently unsetting the cookie in your example. Also, setting a cookie with no value is the same as deleting it. Then simply redirect to your landing page after logout.

setcookie( 'cookie_name'); // deletes the cookie named cookie_name
Header("Location: url.com");
