Displaying result while still processing.....

[Clouds®]

Hi all,

Strange topic, I'll explain it:

I have a page with a for-loop that takes a long time to execute.
In this loop, a line of data is printed using printf (or echo).

I currently see the printed data only after completion of the for-loop.
What I'd like to have is that each bit of data that is printed in the loop,
displays at once, so that I can see the progress of the loop...

Is there a way to achieve this?

TIA for your help!

while () {
echo "fkjfijij\n ";
flush();
}

Thnxz...
For some reason (IE 6.0? XP Pro? webserver?) this still doesn't do the
trick...
Any other options?

See if this helps:

...
flush();
ob_flush();

I sometimes find one on its own doesn't work but when you use both of them
it usually does. Also make sure any output you have has line breaks before
doing the flush as this sometimes seems to make a difference.

Apart from what you've already been told, check source code in your
browser. Sometimes they won't display a page until it's fully loaded (esp.
in there're tables involved).
