I created library of PHP5 functions that use $_SESSION. Which solution
is better:
1. Add session_start() at the top of library file
2. Add a comment that library users shoud call session_start().
Please help. I have little experience in PHP5.

I would say that you should require the user to issue the
session_start() call. A couple of reasons:
1. Your library may not be included at the start of the page, and
session_start() will fail if ANY output is produced before the call.
2. The user may issue his/her own session_start() call, in which case
the second call (whichever it may be) will fail.
Libraries shouldn't do anything other than what they are told to do with
no side effects; in this case your library hasn't been told to issue the
session_start() call.
