Actually, your message sparked an idea in my [slow] mind. :)
I can put the PHP code in a java script, and tell javascript to call
it
every fifteen seconds. Best option, I think. :)
Any ideas?
Thanks!

hi...
is this a php/web based app...
are the users using the chat function via the browser..
if this is a browser/web app, are you looking for a way for the
php web app to refetch the textfile... i would assume so...
have you figured out a rough architecture/design for your app..
in your design, you're going to need to figure out how to
accomplish updates to the text file, and when you do, you'll
also have figured out how to do the reads...
i'm assuming that you don't want a continuously running thread
for your php/web app.. ie one continuously, never ending loop...
-so you'll have the user add some text, the app will write this to
a file..
the user will either select a refresh kind of btn, or your
app will have to implement a refresh process, which will then
fetch new/updated data from your files..
etc...

Subject: Re: Periodic Actions in PHP?
Hi,
I'm going to create a small chat script with PHP. The messages you
want
others to see
will be added to a flat file (I.E. TXT file), and read and
displayed by
PHP. However, I want
this reading and displaying to be periodic. This means that I want
PHP to
check the file for
new lines every,say, fifteen seconds. How may I do that? I have been
unable to find any
function that acts like a timer.
If you're on Unix then look into using cron. Type the following at
the
command prompt to get info on cron:
man 5 crontab
Cron tasks can be scheduled at most once per minute. And if you're
using Windows then I believe the equivalent would be task scheduler,
but I've no idea how you would go about using it.
