You may want to destroy the session using the session destroy function (if that's what it's called).

Personally, I don't use sessions, but if I did, I'd probably just ditch the session.

You could also try manually clearing their cookies - loop through $_COOKIE (or whatever it's called - CHECK that.) and set each cookie with an expiry date of long ago.

Of course you might have some non-session (i.e. persistent) cookies you want to keep.

some version of PHP have issues un unsetting arrays...

To wipe it, use session_destroy() or simply $_SESSION=array()

For a complete logout you need to use all of the following

//--- LOG OUT button clicked - destroy session	
if (isset($_REQUEST['log_out'])) {  

  	$_SESSION = array();
  	session_destroy;
}

That first empties the session array and then kills it. If you don't empty the session array then it will not be destroyed.

i dont want to empty the whole session coz i have another values in the session
i just want to empty specific value

[crazychris]

$_SESSION['Login_Name']=false;

I don't know if you're forgetting to use session_start but i've seen many people do just that so i put it here. Also before redirecting (especially for redirects) to the next page, you need to call session_write_close() to ensure the session data has been saved.

session_start();
if(isset($_SESSION['Login_Name'])) {
    unset($_SESSION['Login_Name']);
    session_write_close();
// redirect code goes here
}
