我有专用的服务器，因此可以进行更改.我正在运行apache和nginx作为代理服务器.

I have a dedicated server so I can make the changes. I am running apache and nginx as the proxy server.

推荐答案

您正在使用ob_flush而没有ob_start，因此没有需要冲洗的东西.

You're using ob_flush without ob_start, so there is nothing to flush for it.

这还取决于Web服务器和代理及其设置.

It also depends on the webserver and proxy and its settings.

您应禁用Nginx的缓冲(将proxy_buffering off;添加到配置文件并重新启动Nginx)

You should disable buffering for Nginx (add proxy_buffering off; to the config file and restart Nginx)

还要检查您的 php.ini 是否包含output_buffering = Off和zlib.output_compression = Off.

Also, check if your php.ini contains output_buffering = Off and zlib.output_compression = Off.
