Don't believe everything you read on the internet!

flush() will flush the PHP buffers to the server. But PHP can't control
what happens to the data after that. The server can buffer the data, it
can be cached by proxies between the server and the client, and the
client will buffer the data. The client may or may not display the data
before all of it arrives.

It's not like a C application where the application can flush data
directly to the screen.
