it's nothing special simple flat file database engine(if i may call it that way, lol)

Usage

PHP Code:

---

$TextDB       = new TextDB('db_file.db.php',array('id','title','author','language','date','content'));

foreach($this->getTextDB->getAllItems() as $news)
{
    TWE_Template::writeNews($news['title'],$news['content'],$news['author'],$news['date']),$news['language']);
}
        
                        $registerID = time();
                        $registerData = array
                        (
                            'id'                => $registerID,
                            'account'           => $_POST['user_nick'],
                            'firstname'         => NULL,
                            'lastname'          => NULL
                        );

                        $this->getUserDB->Insert($registerID,$registerData);
                        $this->getUserDB->save();
