Thanks for your answer, Gustav,
now I see I didn't explain good enough what my problem is.
My problem is not how to construct a status bar, but not it is
possible to provide any output before the headering (*Warning*: Cannot
modify header information - headers already sent by). Neither after it.
Best regards
Sabine
P.S.: I played around with PEARs HTML_Progress. It's really worth
trying. The user doc on Laurent Lavilles page provides a lot of
explanation and examples.
(http://pear.laurent-laville.org/HTML_Progress/).
Hi Sabine
why don't you try an AJAX approach? (Kinda like GMail and stuff like
that?)
You can create a DIV in your page that contains the *output* (maybe an
image with the width set to the percentage of mails sent): the content
of this DIV is updated by another script (the one that sends the email)
that gets called (via JavaScript) at specific intervals with a specific
query (in your case, the messages to send). This way your main page
never gets reloaded and you see a nice progress bar in your DIV.
I know it sounds a bit difficult, but it's a cool "technology" and after
the initial difficulties it can be really useful. As a start, have a
read here: http://en.wikipedia.org/wiki/AJAX
HTH, cheers!
Silvio

Look at the functions ob_start() and ob_flush()..
Something like:
<?php
ob_start();
