This function attempts to push current output all the way to the browser with a few caveats:

flush() has no effect on any client-side buffering in the browser
Results vary by browser: different browsers have different requirements for displaying anything before the end of the script or page
To overcome these browser buffering issues and obtain immediate display, you may have to send a minimum amount of data, an end-of-line (EOL) character or an html tag
See http://php.net/manual/en/function.flush.php for more insight into differences between browsers and the use of flush()
