I need to build a php-chat (online support system), but in realtime.
I've develope a system that refresh in browser client in 5 seconds. But
i need a system that works in realtime, what i meen is when a client or
the server send a message, the browser refresh when a message was sent.
All this without JAVA.

thanx

The server can controll the Refresh and the cache expiry through headers
sent when the page is requested by the client.

add this to expire client content every time a request for the same page is
sent.
header("Pragma: no-cache");

add this to refresh client content every 5 sec
<meta http-equiv="Refresh"
content="5;URL=http://www.doamin.com/page.phtml">.

Have you thought about using a pre-built system:

http://www.phplivesupport.com/web/phplive_web/

It does cost money (one-time fee, no recurring fee), but I would imagine
that spending time to build one yourself would also cost money (in terms
of time).

I have never used it, but it definitely looks to be worthwhile.

it's kinda impossible since HTTP is a STATELESS PROTOCOL

ircg is a lot of fun and could be used as the server system for message
management, the real problem is how to get the data to the client without
use of a socket

ircg also needs an ircd which is a little to bloated[1] for a simple
solution for a realtime chat :)

/me is taking a extra jolt on ircg :)

If you don't close the connection with the client you can use flush() to
send accumulated data.

Exampel:
Start the webpage
flush() // sends initial data

while (conversation in progress) {
if (newdata found) {
echo "newdata";
flush();
}
sleep(a while);
}

end page

I've been tinkering with PHP-GTK of late and just the other day it occurred
to me that some sort of messaging client would be a great way to get my feet
wet - by authoring in PHP on the client side (instead of trying to kluge
something together in a web browser), sockets would cease to be a problem.
:) I hadn't really considered the particulars of setting up a PHP script to
essentially act as a messaging "server", so your posts have been quite
instructive. Thanks!
