Answer 1

You need to include session_start() at the top of your file then your function will surely work.

Answer 2

1) You have used $rows in function, what is that variable?
2) yes, you can include that file in all pages, but better you create session.php under lib folder and include that file in lib/config.php. So you just need to include config.php in all pages.
3) You need session_start() at very top most code of your php file.

Answer 3

What is the use of creating session.php file?
You can access session like that:
#session_start();
if you want to write new session than use like that $_SESSION['MySession'] = 'XYZ';
Accessing Session echo $_SESSION['MySession'];
You can access session $_SESSION['MySession'] on every page but you need to include #session_start() at the top of every php file.
