where does it go?

[deep]

Hello,

im building a very small forum and when an user logs in i need to "save" ths users id in a global variable so that i can easily access it on every page. For this i use:

session_start();
if (!isset($SESSION['id'])) {
$SESSION['id'] = $id;
} else {
$id = $_SESSION['id'];
}

And it was working fine untill i found a very strange 'bug'. I left my browser on (twice) with my page loaded in it. When i came back 1-2 hours later and click on refresh button something very strange happens... everything that is using the $id stops working and when i try to print the $id at this state i get nothing!! Empty?!?!

The only solusion is to close the browser and open a new one...

Pls help!

Thanks!

Did you register the variables into the session? I don't see in your code that you did. If you don't register the variables into the session, then it is like you never had session variables.

But if i didnt register it... why did it work the first hour??

sessions time out

session.gc_maxlifetime integer
session.gc_maxlifetime specifies the number of seconds after which data will be seen as 'garbage' and cleaned up.
