                    $play_id = $worksheet->getCellByColumnAndRow(3, $row)->getValue();
                    $mem_name = $worksheet->getCellByColumnAndRow(4, $row)->getValue();
                    $data[] = array(
                        'group' => $group,
                        'merchant_id' => $merchant_id,
                        'login_id' => $login_id,
                        'play_id' => $play_id,
                        'mem_name' => $mem_name,
                    );
                }
            }
            $this->db->insert_batch('excel_files', $data);
        }
    }

This code is working when upload excel, but I wonder when user upload excel 50 rows, the day after upload again 65 rows, the 65 rows no need to duplicate.

you can do some check, in your looping code

public function import_excel(){
        if (!$_FILES["file"]["name"]) {
            echo "Please upload excel file !";
        } else {
            $path = $_FILES["file"]["tmp_name"];
            $object = PHPExcel_IOFactory::load($path);
            foreach ($object->getWorksheetIterator() as $worksheet) {
                $highestRow = $worksheet->getHighestRow();
                $highestColumn = $worksheet->getHighestColumn();
                for ($row = 2; $row <= $highestRow; $row++) {
                    $group = $worksheet->getCellByColumnAndRow(0, $row)->getValue();
                    $merchant_id = $worksheet->getCellByColumnAndRow(1, $row)->getValue();
                    $login_id = $worksheet->getCellByColumnAndRow(2, $row)->getValue();
                    $play_id = $worksheet->getCellByColumnAndRow(3, $row)->getValue();
                    $mem_name = $worksheet->getCellByColumnAndRow(4, $row)->getValue();
                    $data[] = array(
                        'group' => $group,
                        'merchant_id' => $merchant_id,
                        'login_id' => $login_id,
                        'play_id' => $play_id,
                        'mem_name' => $mem_name,
                    );
                }
            }
            //-- check duplicate here
            $dataCheck = $this->methodCheck($data);
            if($dataCheck==true)
            {
                 $this->db->insert_batch('excel_files', $data);
            }
        }
    }   
    
    function methodCheck($param){
        $this->db->select("*");
        $this->db->from("yourInsertedTable");
        foreach($param as $searchKey=>$searchValue){
            $this->db->where($searchKey,$searchValue);
        }
        $hasil=$this->db->get('')->result_array();
        if(isset($hasil))
        {
            return false;
        }else{
            return true;
        }
    }
