[FX.php List] Extending Session Expiration

[Jonathan Schwartz]

Hi Gary,

I've never messed with the system settings.  I just set the session 
as follows once the user logs in.  This codes only gets executed once.

$_SESSION['sess_start_time']= time();
$_SESSION['sess_exp_time']=time() + 3600;

Then, whenever a user advances to a new page in session, I test for 
expired session:

if(time() >= $_SESSION['sess_exp_time'] ){
	Do this; //exit or some other action.
}

Works for me.
