Php 我正在尝试从mysqli数据库导出excel工作表中的数据，但无法在多个工作表中序列化S No，如1、2、3..等？,php,mysqli,phpexcel,Php,Mysqli,Phpexcel,下面是我的代码。我想序列化的S号，因为我得到的S号根据数据库。我附加的屏幕截图excel文件以及。任何帮助将是伟大的为我。[ 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')

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++;
        }
在迪潘维塔的帮助和支持下，我终于发布了我的答案。。 我已经为第一张做了解决方案，也可以为第二张做同样的解决方案

cnt的值没有增加..为什么会这样？请在
foreach（）的末尾检查。
已经尝试过了，但值没有增加，它每行只打印1个。根据您的评论更改后，我上传了一个图像，但它也不起作用..与您提到的一样。这个代码示例确实帮助了我。谢谢！
