Sessions And Stuff

[Guest Stefán Örvarr Sigmundsson]

I'm having a lot of trouble with sessions.1. I seem to be unable to destroy the sessions I create.2. When I check to see if my 'lang' session has been set (with the isset function) it tells me the session has not been set, but still I am able to get the contents of it by writing echo $_SESSION['lang'];3. Why doesn't this work for Firefox: $_SERVER["HTTP_ACCEPT_LANGUAGE"]?Should I abandon PHP altogether?

1. I seem to be unable to destroy the sessions I create.

You could do this:$_SESSION = array();but that's going to remove all session information, not just yours (which only applies if there are several things using sessions on the same server). When I log someone out or otherwise get rid of the session I just unset the specific things I set.unset($_SESSION['userid']);

2. When I check to see if my 'lang' session has been set (with the isset function) it tells me the session has not been set, but still I am able to get the contents of it by writing echo $_SESSION['lang'];

There's something wrong with the code, it won't tell you a variable is not set if it has a value. Are you using isset before session_start?

3. Why doesn't this work for Firefox: $_SERVER["HTTP_ACCEPT_LANGUAGE"]?

Not all browsers send the same set of HTTP headers, your copy of Firefox might not be sending the accept-language header.
