Controller:
 

load->model('TestImportExcel_model','testimportexcel_model');
		}

		public function importexcel(){
			if ($_FILES['file']['name']) {
				$tmp_file = $_FILES['file']['tmp_name'];
				$file_types = explode('.', $_FILES['file']['name']);
				$file_type = $file_types[count($file_types)-1];
				
				//判断是否为excel文件
				if (strtolower($file_type) != 'xlsx') {
					echo "不是excel文件，请重新上传！";
				}

				//设置上传路径
				$savePath = "./uploads/";
				//文件命名
				$str = date('Ymdhis');
				$file_name = $str.".".$file_type;
					if (!copy($tmp_file,$savePath.$file_name)) {
						echo "上传失败";
					}
					$this->load->library('PHPExcel');
					$objPHPExcel = new PHPExcel();
					$objProps = $objPHPExcel->getProperties();
					$objReader = PHPExcel_IOFactory::createReader('Excel2007');
					$objPHPExcel = $objReader->load($savePath . $file_name);
					$sheet = $objPHPExcel->getSheet(0);
					$highestRow = $sheet->getHighestRow();
					$highestColumn = $sheet->getHighestColumn();

					//excel中的一条数据
					$excel_data = array();
					for ($currentRow=2; $currentRow <= $highestRow; $currentRow++) { 
						for ($currentColumn='A'; $currentColumn <= $highestColumn ; $currentColumn++) { 
							$excel_data[$currentColumn]=$objPHPExcel->getActiveSheet()->getCell($currentColumn . $currentRow)->getValue();
						}
						$this->testimportexcel_model->insert_excel($excel_data['A'],$excel_data['B']);
					}

					echo "导入成功";
			}
		}
	}
?>

model:

load->database();
		}

		//插入数据到数据库
		public function insert_excel($main_question,$answer){
			$data = array(
				'main_question'=>$main_question,
				'answer' => $answer,
			);
			$this->db->insert('question_answer',$data);
	    }
