        //创建连接
        $conn = mysqli_connect($servername,$username,$password,$dbname);
        //检测连接
        if(!$conn){
            die('连接失败:'.mysqli_connect_error());
        }
        $newExcel = new Spreadsheet();  //创建一个新的excel文档
        $objSheet = $newExcel->getActiveSheet();  //获取当前操作sheet的对象
        //设置宽度为true
        $newExcel->getActiveSheet()->getColumnDimension('A')->setWidth(3);
        $newExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);

        $objSheet->setCellValue('A1', '名称')
                 ->setCellValue('B1', '图片');
        //获取数据库的数据。
        $sql = "SELECT id,title FROM feiyi_protection ORDER BY ftype ASC,fwords ASC";
        $k = 2;
        $result = mysqli_query($conn,$sql);
        $dataArray = [];
        while ($val = mysqli_fetch_assoc($result)) {
            $objSheet->setCellValue('A' . $k, $val['title']);    //数据行
            // 获取本地文件夹路径
            $dir = __DIR__.'/poster/code/';
            $file_info = $val['id'].'.png';

            $drawing[$k]->setWorksheet($newExcel->getActiveSheet());
            // 每行高度设置
           $objSheet->getRowDimension($k)->setRowHeight(80);
           $k++;
      }
      downloadExcel($newExcel, '表1', 'Xls');
}
