<?php
for ($i=1;$i<50;$i++) {
for($ii=1;$ii<$i;$ii++){printf("X");}
flush();
sleep(1);
printf("<BR>");}
?>
</html>

The script does not show row of "X" setep-by-step, but processes it and shows outcome at once.

php flush() only flushes it internal output buffers
it has no influence on web server buffering or proxies

especially on windows the output is always completely
buffered until script termination AFAIR
