How to tell if a session is active?

Question

Per request, there are a few different ways that you can tell whether or not a session has been started, such as:

$isSessionActive = (session_id() != \"\");
         


        

Answer 1

I worked around this by adding a couple wrapper functions around the various session creation/closing/destroying functions. Basically:

function open_session() {
     session_start();
     $_SESSION['is_open'] = TRUE;
}

function close_session() {
   session_write_close();
   $_SESSION['is_open'] = FALSE;
}

function destroy_session() {
   session_destroy();
   $_SESSION['is_open'] = FALSE;
}

function session_is_open() {
   return($_SESSION['is_open']);
}

Hackish, but accomplished what I needed.
