You can't reliably write output to the browser. You can flush the PHP
buffer, but the web server also has a buffer - and it won't send data
until its buffer is filled. Also, the browser won't necessarily show
incomplete data - again, depending on the browser.

You don't find much on PHP threading because you don't typically do
multithreading in PHP. Most PHP scripts (especially web based) are
meant to be short and sweet - get in, do the job and get out.

If you really require such a function, you may have to look at other
languages - a java applet can easily do what you want, for instance.
