Does SMF start the session()?

[rcane]

I was going to experiment/learn using _session['variables'] but didn't want to throw an error by calling it twice.


Ohh, disregard.  just learned out to see.

So, a little more information.

Yes, SMF starts the session with session_start(). $_SESSION is empty before that is invoked in every case.

If you try to start a second session while the first is active, it won't throw an error but results will be... unhelpful.

You can rely on SMF having opened the session on any SMF page including SSI, loadSession() is one of the earlier functions called.
