Answer 1

if you use:

session_set_cookie_params(0);
session_start();

Your session cookie will destroy when the browser is closed... so your session will be good until they close the browser. IE. You login, and you are logged in, you close the browser, re-open it, go to the site again, and you wont be logged in.
