i made this function:

	function Online ( )
	{
		define('IN_PHPBB', TRUE); 
		$phpbb_root_path = 'forum/'; 
		include($phpbb_root_path . 'extension.inc'); 
		include($phpbb_root_path . 'common.'.$phpEx); 
		
		// 
		// Start session management 
		// 
		$userdata = session_pagestart ( $user_ip, PAGE_INDEX ); 
		init_userprefs ( $userdata ); 
		// 
		// End session management 
		//
		
		if( $userdata['session_logged_in'] ) 
		{ 
			return TRUE;
		} 
		else 
		{ 
			return FALSE;
		}
	}

and called it like:

if ( $Func->Online ( ) )
{
	echo 'boo!';
}

but i get this error:


Fatal error: Call to a member function on a non-object in /home/luke06/public_html/forum/includes/sessions.php on line 134

but the code out side of a function works perfect. Any ideas
