Hey all,
I am using the Zhang session method from
http://www.phpbuilder.com/columns/ying20000602.php3 and it works great
with a mysql database.
Does anyone out there know how to tell if a session is expired using
this method? The Read Session function is:
\\---------------------------------------;
function sess_read($key) {
global $SESS_DBH, $SESS_LIFE;
$qry = "SELECT value FROM Sessions WHERE sesskey = '$key' AND expiry >
" . time();
$qid = mysql_query($qry, $SESS_DBH);
if (list($value) = mysql_fetch_row($qid)) {
return $value;
}
return false;
}
\\---------------------------------------;
So if session is expired, this script will return nothing (per the
expiry WHERE clause).
Say I had placed a variable called $NameOfUser in the session data using
session_register($NameOfUser), if the session is expired, would I be
able to know that it was expired by using isset($NameOfUser) after
running the session_register($NameOfUser) in the script??
Thanks.
