I am learning php4 sessions. I noticed that the way to check if there is a
"current session" is not given clearly. Say I started a session after the
guy signed in by session_start() and registered some variables. At some
other page, I want to check if the user is signed in or not.
Seems like I can use
if ( session_is_registered("my_previously_registered_variable")) { // let
the user see the page...
or
if ( SID ) { // let...
or
if (session_id()) { // let...
How do I do it best?
Thanks.
