You can't do it reliably.

You can control what your code does. You can even control the PHP
buffering. But you can't control buffering in the web server, which may
delay the output until the buffer fills or the entire page is sent. You
also cannot control the browser, which may delay displaying the data
until the entire page is received.

You can flush buffers and get it to work much of the time. But not
necessarily all the time.
