If i use session in my php code then for how much time the session will be valid...

 

And how can i change the length of the session...

session information is temporary and is usually deleted very quickly after the user has left the website that uses sessions.

Yeah thats true.. whenever user leaves the site the session expires....

 

But what if the user opened the website and leave it... then for how much time session will be valid....

 

And how can i change its time.... that after 5 min when user will refreshed he logged in will he will be logged out.....

You can set the set timeout period then destroy the session.

You can also delete the actual session file if you know exactly where it is (you can set the path where the session files are stored in php.ini). I use this on my intranets when I want to force a user to be logged out.

 

when they login I store their session id:

session_start();
$sid = 'sess_'.session_id();

 

and to force logout I use something like this:

$file = '/phpsessions/'.$sid;
if(is_file($file)){
unlink($file);
}
