我正在尝试从 mysqli 数据库导出 excel sheet 中的数据，但我无法在多个 sheet 中序列化 S No，如 1,2,3..etc？

Question

下面是我的代码。我确实想序列化 S 号，因为我正在根据 DB.I 获得 S 号，我附上了 excel 文件的屏幕截图，因为 well.Any 帮助对我来说非常有用。[!我已经在图片中提供了我的查询。希望你有问题。 []2

Answer 1

请更新此部分并尝试：

    while ($row_q = mysqli_fetch_assoc($q)) {
            $i = 0;$cnt=1;
            foreach ($row_q as $key => $value) {
                if ($key == 'location')
                    continue;
                if($key == 'id')
                {
                  $objPHPExcel->getActiveSheet()->setCellValue($columns[$i] . $row, $cnt);
                }
                else {

                $objPHPExcel->getActiveSheet()->setCellValue($columns[$i] . $row, $row_q[$key]);
    }
                $i++;
            }
$cnt++; //this part is missing
            $row++;
        }

在 Dipanwita 的帮助和支持下，我终于发布了我的答案.. 我已经完成了第一个 sheet 的解决方案，第二个也可以这样做。
