Hi all, My problem

foreach ($results as $key => $item) {
                    if ($key > 9) {
                        $MaSV = array(
                            'MaSV'      => $item[1],
                            'MaKhoaHoc' => $MaKhoaHoc,
                            'MaHeDaoTao'=> $MaHeDaoTao,
                            'MaKhoa'    => $MaKhoa,
                            'MaNganh'   => $MaNganh,
                            'MaLop'     => $MaLop,
                            'HoSV'      => $item[2],
                            'TenSV'     => $item[3],
                            'NgaySinh'  => $this->getFormat($item[5]),
                            'NoiSinh'   => $item[6],
                            'Email'     => $item[1].'@gmail.com',
                            'DiaChiTamTru'=>'Chua Xac Dinh',
                            'GhiChu'    => $item[3],           
                        );
                        echo "<pre>";
                        print_r($MaSV);
                        if($Hososinhvien->save($MaSV)==false) {
                        $this->flash->error("Oh No!");
                        }
                        $this->flash->error($Hososinhvien->getMessages());
