好的，下一个 PHPExcel 问题。我有一个用户填写的 HTML 表单，数据将被发送到数据库。所有这一切都没有问题。我正在使用 PHPExcel 将该信息发送到 Excel 工作表，以便该组织的总裁可以查看已发送的报告（他选择在 Excel 中使用它）。当他单击按钮时，信息将下载到 Excel。这一切都很好，除了工作表的第一行被标题信息覆盖。我知道它是标题，因为如果我更改 $headings 并删除数组中的值，隐藏查询的一部分就会显示出来。

我从以下网址获得此代码：http: //phpexcel.codeplex.com/discussions/246121/

可能存在编码错误，或者我可能没有将所有文件和类上传到互联网......

任何帮助表示赞赏。谢谢。

在此代码中，您确实有两个循环遍历结果集，一个从第 1 行开始，然后用标题覆盖第 1 行，然后再次循环遍历结果集（实际上不会循环，因为您已经到达末尾第一个循环中的结果集）从第 2 行开始
