[snip] Is there a way for the server to notify the client about an event, provided the client was online in the past X minutes? To elaborate: A client comes online. A script PHP executes (serves the client), and terminates. Now if a new event occurs, how can the server notify the client about that event? [/snip] You would need a connection with state to do that, web server connections are stateless. The client would have to have a 'listener' waiting for some event to be pushed to them and then the listener would take an action. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
