RE: [PHP] SESSIONS lost sometimes

Thanks Ashley. Will implement if the need arise again.. By limitation I actually meant "annoyance". "Limitation" was the wrong word to use. (I think all browsers has something great and something not so great) :-) Greetings -----Original Message----- From: Ashley Sheridan [mailto:ash@ashleysheridan.co.uk] Sent: 20 August 2009 12:05 PM To: Leon du Plessis Cc: 'Nitebirdz'; php-general@lists.php.net Subject: RE: [PHP] SESSIONS lost sometimes On Thu, 2009-08-20 at 12:04 +0200, Leon du Plessis wrote: > Thanks Ashley, > > I just want to iterate again that when a new page is opened by another > existing page in a new browser or Tab, the session_id is already created and > therefore the current way browsers work is in no way compremised.

So for example, it might look something like this: $_SESSION['your_app_name']['username']['some_value'] This way, if the username doesn't exist, you know there is no session for them. It's ugly, but it will get around what you see as a limitation.
