PHP implements a bunch of session handling functions. If you desire you
can use the session ID from these to retrieve a record from the
database.
For myself, I have developed my own session handling, rather than use
PHP's. This was perhaps not a good choice, but it is a path I went down
some years ago now and it is hard to change :-)
PHP sessions do not require the database to be there, of course,
allowing you to stuff information into an in-memory session structure,
but this limits the amount of information that can be associated easily.
My own session management does use the database to hold session- and
user- related information, retrieving (and possibly updating) for each
page the user visits during their session.

Andrew.
