The code seems wrong. Although, it can work. It depends on php.ini.

You must start session before output anything to browser, or you must use
buffering to do this,
or you must use URL mode for session.
i.e. This code sends "<html><body>" before starting session and cookie header
must be sent before if session is cookie mode.
I recommend to write session_start() before programmers do anything.

I'm not sure what do you want to handle "it".
Starting session can handle in php.ini and inside code.

No.
Session will be started automatically, so programmer does not have to write it.
I recommend to write session_start(), though.
Also, session will be started implicitly if programmer uses session functions
even without setting session.auto_start to true. It should work, if programmer
didn't send any output to browser before. i.e. Programmer does not even have to
write session_start() even if session.auto_start is false. I don't recommend it,
though.

It seems works fine on my box without it when I use $HTTP_SESSION_VARS at least.
I think it will not work without $HTTP_SESSION_VARS.
