thinkphp实现excel数据的导入导出（附完整案例）

实现步骤：
一：在http://phpexcel.codeplex.com/下载最新PHPExcel放到Vendor下，注意位置：ThinkPHP\Extend\Vendor\PHPExcel\PHPExcel.php。
二：导出excel代码实现

    /**方法**/
    function  index(){
            $this->display();
        }
    public function exportExcel($expTitle,$expCellName,$expTableData){
            $xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称
            $fileName = $_SESSION['account'].date('_YmdHis');//or $xlsTitle 文件名称可根据自己情况设定
            $cellNum = count($expCellName);
            $dataNum = count($expTableData);
            vendor("PHPExcel.PHPExcel");
          
            $objPHPExcel = new PHPExcel();
            $cellName = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','AA','AB','AC','AD','AE','AF','AG','AH','AI','AJ','AK','AL','AM','AN','AO','AP','AQ','AR','AS','AT','AU','AV','AW','AX','AY','AZ');
            
            $objPHPExcel->getActiveSheet(0)->mergeCells('A1:'.$cellName[$cellNum-1].'1');//合并单元格
           // $objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', $expTitle.'  Export time:'.date('Y-m-d H:i:s'));  
            for($i=0;$i<$cellNum;$i++){
                $objPHPExcel->setActiveSheetIndex(0)->setCellValue($cellName[$i].'2', $expCellName[$i][1]);
            }
              // Miscellaneous glyphs, UTF-8  
            for($i=0;$i<$dataNum;$i++){
              for($j=0;$j<$cellNum;$j++){
                $objPHPExcel->getActiveSheet(0)->setCellValue($cellName[$j].($i+3), $expTableData[$i][$expCellName[$j][0]]);
              }            
            }  
            
            header('pragma:public');
            header('Content-type:application/vnd.ms-excel;charset=utf-8;name="'.$xlsTitle.'.xls"');
            header("Content-Disposition:attachment;filename=$fileName.xls");//attachment新窗口打印inline本窗口打印
            $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');  
            $objWriter->save('php://output');
            exit;  
        }
    /**
         *
         * 导出Excel
         */
        function expUser(){//导出Excel
            $xlsName  = "User";
            $xlsCell  = array(
            array('id','账号序列'),
            array('truename','名字'),
            array('sex','性别'),
            array('res_id','院系'),
            array('sp_id','专业'),
            array('class','班级'),
            array('year','毕业时间'),
            array('city','所在地'),
            array('company','单位'),
            array('zhicheng','职称'),
            array('zhiwu','职务'),
            array('jibie','级别'),
            array('tel','电话'),
            array('qq','qq'),
            array('email','邮箱'),
            array('honor','荣誉'),
            array('remark','备注')    
            );
            $xlsModel = M('Member');
        
            $xlsData  = $xlsModel->Field('id,truename,sex,res_id,sp_id,class,year,city,company,zhicheng,zhiwu,jibie,tel,qq,email,honor,remark')->select();
            foreach ($xlsData as $k => $v)
            {
                $xlsData[$k]['sex']=$v['sex']==1?'男':'女';
            }
            $this->exportExcel($xlsName,$xlsCell,$xlsData);
            
        }

第三：导入excel数据代码

    function impUser(){
            if (!empty($_FILES)) {
                import("@.ORG.UploadFile");
                $config=array(
                    'allowExts'=>array('xlsx','xls'),
                    'savePath'=>'./Public/upload/',
                    'saveRule'=>'time',
                );
                $upload = new UploadFile($config);
                if (!$upload->upload()) {
                    $this->error($upload->getErrorMsg());
                } else {
                    $info = $upload->getUploadFileInfo();
                    
                }
            
                vendor("PHPExcel.PHPExcel");
                    $file_name=$info[0]['savepath'].$info[0]['savename'];
                    $objReader = PHPExcel_IOFactory::createReader('Excel5');
                    $objPHPExcel = $objReader->load($file_name,$encode='utf-8');
                    $sheet = $objPHPExcel->getSheet(0);
                    $highestRow = $sheet->getHighestRow(); // 取得总行数
                    $highestColumn = $sheet->getHighestColumn(); // 取得总列数
                    for($i=3;$i<=$highestRow;$i++)
                    {  
                       $data['account']= $data['truename'] = $objPHPExcel->getActiveSheet()->getCell("B".$i)->getValue();  
                        $sex = $objPHPExcel->getActiveSheet()->getCell("C".$i)->getValue();
                       // $data['res_id']    = $objPHPExcel->getActiveSheet()->getCell("D".$i)->getValue();
                        $data['class'] = $objPHPExcel->getActiveSheet()->getCell("E".$i)->getValue();
                        $data['year'] = $objPHPExcel->getActiveSheet()->getCell("F".$i)->getValue();
                        $data['city']= $objPHPExcel->getActiveSheet()->getCell("G".$i)->getValue();
                        $data['company']= $objPHPExcel->getActiveSheet()->getCell("H".$i)->getValue();
                        $data['zhicheng']= $objPHPExcel->getActiveSheet()->getCell("I".$i)->getValue();
                        $data['zhiwu']= $objPHPExcel->getActiveSheet()->getCell("J".$i)->getValue();
                        $data['jibie']= $objPHPExcel->getActiveSheet()->getCell("K".$i)->getValue();
                        $data['honor']= $objPHPExcel->getActiveSheet()->getCell("L".$i)->getValue();
                        $data['tel']= $objPHPExcel->getActiveSheet()->getCell("M".$i)->getValue();
                        $data['qq']= $objPHPExcel->getActiveSheet()->getCell("N".$i)->getValue();
                        $data['email']= $objPHPExcel->getActiveSheet()->getCell("O".$i)->getValue();
                        $data['remark']= $objPHPExcel->getActiveSheet()->getCell("P".$i)->getValue();
                        $data['sex']=$sex=='男'?1:0;
                        $data['res_id'] =1;
                        
                        $data['last_login_time']=0;
                        $data['create_time']=$data['last_login_ip']=$_SERVER['REMOTE_ADDR'];
                        $data['login_count']=0;
                        $data['join']=0;
                        $data['avatar']='';
                        $data['password']=md5('123456');              
                        M('Member')->add($data);
            
                    }
                     $this->success('导入成功！');
            }else
                {
                    $this->error("请选择上传的文件");
                }    
            
        }

        <body>
        <P><a href="{:U('Index/expUser')}" >导出数据并生成excel</a></P><br/>
            <form action="{:U('Index/impUser')}" method="post" enctype="multipart/form-data">
