Note: This script displays the contents of $_SESSION (variables stored in the current session) and $_COOKIE (cookies sent by the browser to the server).
For session data to appear, your PHP application must have previously stored data into the session using $_SESSION['key'] = 'value';.
For cookies to appear, they must have been set by your server or another script on the same domain.
