PHP csv 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"); header("Content-Type: application/octet-stream");header("Content-Type: application/vnd.ms-excel");header("Content-Type: application/force-download"); header("Pragma: public"); header("Accept-Ranges: bytes"); header("Expires: 0");header('Content-Disposition: attachment;filename="data.csv"');header("Content-Transfer-Encoding: binary");header("Cache-Control: must-revalidate, post-check=0, pre-check=0");header('Cache-Control: private',false);
回复讨论(解决方案)
header("Content-Description: File Transfer"); header("Content-Type: application/octet-stream");header("Content-Type: application/vnd.ms-excel");header("Content-Type: application/force-download"); header("Pragma: public"); header("Accept-Ranges: bytes"); header("Expires: 0");header('Content-Disposition: attachment;filename=data.csv');header("Content-Transfer-Encoding: binary");header("Cache-Control: must-revalidate, post-check=0, pre-check=0");header('Cache-Control: private',false);
header("Content-Description: File Transfer");
header("Content-Type: application/octet-stream");
header("Content-Type: application/vnd.ms-excel");
header("Content-Type: application/force-download");
header("Pragma: public");
header("Accept-Ranges: bytes");
header("Expires: 0");
header('Content-Disposition: attachment;filename= data.csv');
header("Content-Transfer-Encoding: binary");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Cache-Control: private',false);
header("Content-Description: File Transfer");
header("Content-Type: application/octet-stream");
header("Content-Type: application/vnd.ms-excel");
header("Content-Type: application/force-download");
header("Pragma: public");
header("Accept-Ranges: bytes");
header("Expires: 0");
header('Content-Disposition: attachment;filename= data.csv');
header("Content-Transfer-Encoding: binary");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Cache-Control: private',false); 改了哪里?
但是在服务器就只能直接显示在网页上了
是指代码还是csv的内容。没看出代码有什么问题。

信息不全,不好说,检查下文件的编码格式,是否有BOM头,如果有bom头的话,可能会输出导致之后的header失效。

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
