Hi all, Maybe this is a somehow stupid question. I want to know how php could know whether session_start() has been called, that is, whether session has been started.
you can do it by checking the return value of session_id() if it's empty you can be pretty sure session_start() was not called. having said that I think your better off writing code that can assume the session was started (e.g. by including a file that init's the session [and whatever else is relevant) ... but that may not be doable. see here: http://php.net/session_id I don't recommend the auto_session_start ini setting because there are probably times when you explicitly don't need/want the session started.
I Googled, but got little help. Thank you for help! Any tip is greatly appreciated. Regards, Shelley
