I am doing this, because I am making a text file with a list of all existing sessions. Then another page checks to see if all of these are still active and exist, and if not it will take action and remove the session id from the list. It goes along with the question I asked earlier about the Flash chat program. I figured that I would make a log file of all sessions when a user logs in to chat, then if the user doesn't log out properly (with the log out button) and just closes the browser or shuts off the computer, then their id will be removed from the list, since the session doesn't exist anymore. If there is an easier way to accomplish this, then please fill me in. Here is the Flash chat question I asked earlier with more details for you:
"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." Thanks.

Can this be done? Please let me know if you have any > thoughts. It can be done using the file series of functions. The question is though, why? What passes that session id to you script and why do you need to check to see if the session is still valid or not? PHP automatically detects if a session is not longer valid ... Can you explain more clearly why you want to do this? Maybe we can offer a better way of achieving what you are *really* trying to do :) Jean-Christian Imbeault -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
