Re: [PHP] sessions

[Marek Kilimajer]

The session files are removed by the php engine, this is what happens:
1. You load a page, its suffix is php, apache loads php engine to execute it
2. php engines decides if it is time to clean session cache - the 
probability is taken from session.gc_probability (in %)
3. If yes, it checks each session file's modification time, and if it is 
old, removes it

From this you can see that you need to load some php pages to have a 
chance to see the files removed. If you want them to be removed for 
sure, set session.gc_probability to 100 and load a php page.

Anyway , im doing everything local on my machine , so when  i test php in my
browser i use apache to interpret it , i changed the php.ini file in my
winnt directory
- session.gc_maxlifetime to 15 secs (it was 1440) but the session variables
in my tmp file (on my machine cause its local, file name is
sess_3zdfa4blahblah)

The session file will be deleted automatically by the garbage colector
after certain amount of time, specified in php.ini by
   

session.gc_maxlifetime

Hi,

Im working on a site  where the user logs in , if username and password
matches with uname and pword in database then he is a valid user.
I then start a session with session_onstart() and have a variable for his
username and for his permissions ! (these variables are stored on server)
Once he entered the secrure area , there is a logoff button for the user
     

to
 

log off ! the logoff code looks like

(<?php

session_start();
$name = session_name();
session_unset();
session_destroy();
setcookie($name,"",-3600);
print("<script language='javascript'>self.close();</script>");
?>
)
the above code deletes the cookie on the clients computer + the session
variables on the server !
finally , here is my question ! If the user does not logoff , but simply
closes the browser , the cookie on his computer will be deleted , but the
session
variables on the server will still be there ! How do i delete this ?
Thanks a bunch !

  Shaun
