is there way that?

"how require session function"

use following, example:

if(!isset($_session['session_name'])){ die(); }  

and include session_start(); inside of files used, , @ * top.
(* depending on condition).

for more information on sessions, visit following:

• http://www.php.net/manual/en/features.sessions.php

footnotes:

should faced headers sent... error message later on, can make use of ob_start(); placed above session_start().

for example:

<?php ob_start(); session_start(); // code
