PHP用header进行文件下载
各位，我用header导出csv，我在本地测试可以成功下载导出，但是在服务器就只能直接显示在网页上了，不能下载，为什么会这样？
我的header是这样的：
header("Content-Description: File Transfer"); <br />
header("Content-Type: application/octet-stream");<br />
header("Content-Type: application/vnd.ms-excel");<br />
header("Content-Type: application/force-download"); <br />
header("Pragma: public"); <br />
header("Accept-Ranges: bytes"); <br />
header("Expires: 0");<br />
header('Content-Disposition: attachment;filename="data.csv"');<br />
header("Content-Transfer-Encoding: binary");<br />
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");<br />
header('Cache-Control: private',false);
