从oracle将查询结果导出并下载到PHP中的Excel文件

我在一个PHP页面中尝试了这段代码，以将Oracle的查询结果作为Excel文件下载，但当我浏览到该页面时，它就像挂起的一样是空白和白色的

有什么线索吗？

使用此代码，也可以在本地系统检查文件夹权限中下载excel文件

要下载excel文件，您需要设置标题。因此，只需提供文件名，即下载的excel文件的名称

在您的php文件所在的同一文件夹中，找到将显示的excel不存在。我可以将CityList.xls下载到本地吗？假设PHPExcel.php和de-SELECT都正确。。。远程用户是否有权写入该文件夹？你查过错误日志了吗？谢谢。尝试更新代码。但没有找到CityList.xls文件。在我的本地文件夹或web根文件夹中。使用标题和php://output 将文件发送到web浏览器。。。访问页面时，您是否在浏览器中获得“文件保存”对话框？
