如何利用PHP导入Excel数据到数据库

    /**
     * 导入excel
     * @throws \PHPExcel_Exception
     * @throws \PHPExcel_Reader_Exception
     */
    public function impExcel($filename,$data){
        if (!empty($_FILES)) {
            $config = array(
                'exts'=>array('xlsx','xls'),
                'rootPath'=>"./",
                'savePath'=> "Public/Uploads/$filename/",
                'subName'    =>    array('date','Ymd'),
            );
            $upload = new \Think\Upload($config);
            if (!$info=$upload->upload()) {
                $this->error($upload->getError());
            }

            vendor("PHPExcel.PHPExcel");
            $file_name = $info['excel']['savepath'].$info['excel']['savename'];

            //$objReader = \PHPExcel_IOFactory::createReader('Excel5');

            $Excel_name = getcwd() . '/' .$file_name;

            //$aaa = is_readable($Excel_name);

           // $objPHPExcel = $objReader->load($Excel_name,$encode='utf-8');
            $extension = strtolower( pathinfo($Excel_name, PATHINFO_EXTENSION) );

            if ($extension =='xlsx') {
                $objReader = new \PHPExcel_Reader_Excel2007();
                $objPHPExcel = $objReader ->load($Excel_name);
            } else if ($extension =='xls') {
                $objReader = new \PHPExcel_Reader_Excel5();
                $objPHPExcel = $objReader ->load($Excel_name);
            } else if ($extension=='csv') {
                $PHPReader = new \PHPExcel_Reader_CSV();

                //默认输入字符集
                $PHPReader->setInputEncoding('GBK');

                //默认的分隔符
                $PHPReader->setDelimiter(',');

                //载入文件
                $objPHPExcel = $PHPReader->load($Excel_name);
            }

            $sheet = $objPHPExcel->getSheet(0);
            $highestRow = $sheet->getHighestRow(); // 取得总行数
            $highestColumn = $sheet->getHighestColumn(); // 取得总列数

            for($i=2;$i<=$highestRow;$i++)
            {

                $data['name'] = $objPHPExcel->getActiveSheet()->getCell("A".$i)->getValue();
                $data['tel'] = $objPHPExcel->getActiveSheet()->getCell("B".$i)->getValue();
                $data['zjh']    = $objPHPExcel->getActiveSheet()->getCell("C".$i)->getValue();
                $data['sheng'] = $objPHPExcel->getActiveSheet()->getCell("D".$i)->getValue();
                $data['shi'] = $objPHPExcel->getActiveSheet()->getCell("E".$i)->getValue();
                $data['address']= $objPHPExcel->getActiveSheet()->getCell("F".$i)->getValue();
                $data['money']= $objPHPExcel->getActiveSheet()->getCell("G".$i)->getValue();
                $data['hk_time']= $objPHPExcel->getActiveSheet()->getCell("H".$i)->getValue();
                $data['nanyi']= $objPHPExcel->getActiveSheet()->getCell("I".$i)->getValue();
                $data['uid'] = $_SESSION['user']['id'];
                $data['time'] = date("Y-m-d H:i:s");
                M('release')->add($data);
            }

            $this->success('导入成功！');exit();
        }else
        {
            $this->error("请选择上传的文件");
        }


    }

调用：

 if(IS_POST)
        {
            $data['reason'] = I("post.reason","","trim");
            $data['type'] = I("post.type","","trim");
           // $data['qixian'] = I("post.qixian","","trim");
           // $data['comm'] = I("post.comm","","trim");
            if(!empty($_FILES)){
                $this->impExcel('batch_release',$data);
            }
        }
