Best Practice for wrapping non-class code

Best Practice for wrapping non-class code

What is a good pattern for including and/or wrapping non-classes inside of
a class? For example, I need to use this php file
https://github.com/widop/phpbb3/blob/master/common.php to login to my
phpbb board. Specifically, I need this file to bootload phpbb and then I
will use the $user and $auth variables to login a user. In my code I have
an AuthClient class.
I'm trying to figure out best practice to include common.php from phpbb
and use it inside my class:
class AuthClient implements IAuthClient{
protected $user;
protected $auth;
public function __construct(){
/** Bootloading PHPBB */
define('IN_PHPBB', true);
$phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : './';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);
// Start session management
$this->user = $user;
$this->auth = $auth;
$this->user->session_begin();
$this->auth->acl($user->data);
}
public function login($user_id, $admin, $autologin){
$result = $this->user->session_create($user_id, $admin, $autologin,
true);
}
public function logout(){
$this->user->session_kill();
$this->user->session_begin();
}
}

I believe I've made an improvement, but it is still not working.
