Sleep function for Win32

Anon

When I use the sleep function under Windows 98 (+Apache 1.3.19) with a parameter 1 or higher to slow down output (echo, sleep, echo, ...), the browser (Netscape 4.76) shows nothing while loading the page, then shows all output at once. Can someone help me to put a break between the output lines?

use flush() to force the outputbuffer to be sent to the browser.

echo "hello";
flush();
sleep(1);
echo "here I am";
flush();
sleep(1);

Note: flush() is an expensive (slow) function. Don't use if too often if speed is what you want.

Still the same problem : the browser doesn't display anything while loading the page, then shows all output at once at the end. I've tried both with IE5 and Communicator 4.76, but there were no differences.

Are you using tables an such?

Not at all. I will need to use sleep with more complex output in the future, but right now even an echo (echo "test") doesn't work. Sleep simply doesn't work on my system. When I try to use image files instead of text, I get the same problem.

The script I'm using looks something like this :

<?php
echo "Testline 1";
flush();
sleep(1);
echo "Testline 2";
flush();
?>

Instead of showing the first line, then the second, it just shows both at a time (after about 2 seconds). Increasing the value only causes the page to load longer.
