Hey, I need some advice if anyone is willing to offer it. I have a chat
program I am working on. The interface is built in flash, and it uses
PHP also. There is a main chat area where the users type their messages
back and forth, and there is also a smaller area which displays all of
the currently logged-in users. When a user logs into the chat room, it
adds their nickname to a users.txt file, which creates a list of all the
online users and is then displayed in the chat page. I also have a
logoff button that will search for the users nickname in the users.txt
file and remove it, so that it won't be displayed in the chat window
anymore. The only problem I am having is that if a user doesn't click
on the logoff button and instead just closes the internet window or
shuts off their computer, then their nickname will still appear in the
list of users, since it wouldn't get a chance to be removed by the
logoff button. I'm not sure how to accomplish this, I would appreciate
any help you can offer me. Thanks a lot.
Matt
