PHP 数据库导出Excel表格

1.在项目中创建一个与public同级的extend文件夹

2.下载一个PHPExcel插件放置到项目中的extend文件夹下（下载地址https://github.com/PHPOffice/PHPExcel）

3.调用下面的方法（数据库什么的自行设置）

public function out()

    {

        $path = dirname(__FILE__);

        include_once(EXTEND_PATH . "phpexcel/PHPExcel.php");

        include_once(EXTEND_PATH . "phpexcel/PHPExcel/Writer/Excel2007.php");

        include_once(EXTEND_PATH . "phpexcel/PHPExcel/Writer/Excel5.php");

        include_once(EXTEND_PATH . "phpexcel/PHPExcel/IOFactory.php");

        $objPHPExcel = new \PHPExcel();

        $objWriter = new \PHPExcel_Writer_Excel5($objPHPExcel);

        $objWriter = new \PHPExcel_Writer_Excel2007($objPHPExcel);

        $list = Income::with('user')->where('type',4)->select();

        /*--------------设置表头信息------------------*/

        $objPHPExcel->setActiveSheetIndex(0)

            ->setCellValue('A1', 'ID')

            ->setCellValue('B1', '所属渠道')

            ->setCellValue('C1', '用户ID')

            ->setCellValue('D1', '微信昵称')

            ->setCellValue('E1', '手机号')

            ->setCellValue('F1', '支付宝帐号')

            ->setCellValue('G1', '真实姓名')

            ->setCellValue('H1', '金额')

            ->setCellValue('I1', '用户余额')

        /*--------------开始从数据库提取信息插入Excel表中------------------*/

        $i = 2;

        foreach ($list as $v){

            $objPHPExcel->getActiveSheet()->setCellValue('A' . $i, $v['id']);

            $objPHPExcel->getActiveSheet()->setCellValue('B' . $i, $v['channel_id']);

            $objPHPExcel->getActiveSheet()->setCellValue('C' . $i, $v['user_id']);

            $objPHPExcel->getActiveSheet()->setCellValue('D' . $i, $v['user']['wx_nickname']);

            $objPHPExcel->getActiveSheet()->setCellValue('E' . $i, $v['user']['mobile']);

            $objPHPExcel->getActiveSheet()->setCellValue('F' . $i, $v['user']['alipay_account']);

            $objPHPExcel->getActiveSheet()->setCellValue('G' . $i, $v['user']['alipay_name']);

            $objPHPExcel->getActiveSheet()->setCellValue('H' . $i, $v['money']);

            $objPHPExcel->getActiveSheet()->setCellValue('I' . $i, $v['balance'])

              $i++;

        }

        /*--------------下面是设置其他信息------------------*/

        $fileName = date('YmdH_i_s',time()).'提现信息';

        $objPHPExcel->getActiveSheet()->setTitle($fileName);      //设置sheet的名称

        $objPHPExcel->setActiveSheetIndex(0);                  //设置sheet的起始位置

        $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');  //通过PHPExcel_IOFactory的写函数将上面数据写出来

        $PHPWriter = \PHPExcel_IOFactory::createWriter( $objPHPExcel,"Excel2007");

        header("Content-Disposition: attachment;filename=$fileName.xlsx");

        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');

        $PHPWriter->save(EXTEND_PATH."../public/excel/".$fileName.'.xlsx'); //表示在$path路径下面生成demo.xlsx文件

        $url = $this->request->domain().'/excel/'.$fileName.'.xlsx';

        header('Location:'.$url);

        die;

    }
