Hiya, me again :-) Is it possible to expire certain session data, while still keeping the session itself in tact?
Example... $_SESSION['AlwaysTrue'] = "True"; $_SESSION['ExpireThis'] = "10:20:00"; At 10:19:50 the session is registered. AlwaysTrue must remain True for as long as the session itself is true (as specified in the documentation - this would be until the browser is closed, or after a certain amount of inactive time). However, at 10:20:00 (10 seconds later), I want the ExpireThis value of the session, to be destroyed, without having to de-register the entire session (this would then also destroy the AlwaysTrue value... Am I right in presuming this cannot be done, and I'll have to come up with my own little function to do this with? If so, how can I see at what time a session variable was written, or would I need to register the time that the session variable was set to the session as well? For instance.... $_SESSION['AlwaysTrue'] = "True"; $_SESSION['ExpireThis'] = "10:20:00"; $_SESSION['ExpireThisTime'] = "10:19:50"; Then, just do a comparison, and if ExpireThisTime is past 10:20:00, then just delete that one variable... There's no easier / better way to do this ?? Basically, I'm needing something like this to bring down the number of possible database queries. I have a application which will have new information in a database, every 75 seconds. The queries are performed on every single page that a user is logged in to on a site. To make sure that the same queries is not issued over and over on the database, I want to implement some sort of caching where I will only need to do another query after the database received new information (every 75 seconds). It's all numbers (integers), so I was thinking.... It may well work if I can save these values to session data, and then just "refresh" the session data every 75 seconds.... The problem is, there's lots of other information saved to the session as well, which I cannot afford to loose with a possible session_destroy()...... -- me -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
