Как-то так

function sql($login='root', $pass='', $db='test', $host = '127.0.0.1')
{           
    $dsn = 'mysql:dbname='.db.';host='.$host.';charset=utf8';
    try {
        $this->connect = new PDO($dsn, $user, $password);
    } catch (PDOException $e) {
        echo 'Подключение не удалось: ' . $e->getMessage();
    }
}
