All the emails get re-sent? Or if it hits the 'Stop' button?

Re: [PHP] selfreferencing script with output
Thanks again,Gustav, I tried, but it won't work. The moment of the second headering there had been an output. So you get the error message just an iteration later. Now I reduced the time my script needs. I will check out if it has sufficient time on the productive machine. If so, it won't be necessary to do a selfreferencing script.

Re: [PHP] selfreferencing script with output
Thank you very much for your answer, Rory,
but I fear I don't understand the most important parts of it.
It would be very nice of you if you could give me a further hint, more
explanation.

So I had the idea to write a selfreferencing script like that:

if (($begin+ 50) $allMails) {

But I want to show the user some output like a statusbar (eventually
with pear's Html_Progress) or something like that so he knows the script
is still working.
instead of simply headering the location out, you could simply output
a html page, that has a meta tag to replace it.
What do you mean with that meta tag?
maybe something like
html/head/meta tag here
body
?php
$full_width = 200;
$amt_sent = $_GET['begin'] + 50;
$amt_to_send = 1000;
$img_width = ceil($amt_sent * $full_width / $amt_to_send);
?
img src=pixel.php height=20 width=?php echo $img_width; ?
?php
flush();
send_the_mails();
?
Has anybody of you an idea, a tip for me how to do it?
I don't see how I can do it within the construct above.
Is there an alternative to it?
This doesn't necessarly need to be done using a self-referencing
script. You could have an ajax type system where each script is
accessed sequentially.
And what is an ajax type system? I'm not sure if I don't understand what
you mean due to my lack of english speaking capabilities or if I don't
know the concept.
I assume the last. But additionaly I don't find the word ajax in my
dictionaries or at leo's. Is it an abbreviation?
Kind regards
Sabine

Hi
I don't know if this works, but I think it ought to work:
Set a picture (a line) with width 1, next iteration set the line to
width 2, next to width 3...
OR set a picture with width % off count of mails
Change picture with dhtml (or if you prefer Javascript and css ;-))
