Session data is stored on the server. A cookie is set on the client
with the "session id" which is used to identify which session on the
server to use. So, any changes you make to the $_SESSION array are
written to the session data on the server. In other words, it doesn't
matter what you do after that. The next request will again present the
session id from the cookie and get the latest and greatest data from
the session.
