It recently happened to me too... however, I use the session_id() to keep
track of the same session... I also use a table to check on who's who..
Anyway, it was working fine and all of a sudden the client complained that
no one can log in... I echoed the session id of the pages and saw that
different session ids were being given by SESSION_ID() when the user goes
from one page to another...
Basically, the system thought that each page visited is another session...
when I can the session table, i saw that the user was autheticated ok... and
that the session was log during login.
When he was transfered to the welcome page, the check_session routine,
checked the session_id agaisnt the log and since it gave him a new session
id, the system thought he wasn't logged in and proceeded to ask him to log
again...
Anyway, in both our cases, the session wasn't being kept -- making each page
visit seem a new session...
SOLUTION -- at least for us:
It turns out that their sysad upgraded to the latest PHP and with it came a
new config:
SESSION_ONLY_COOKIES
This is a new config and it was ON and it wasn;t present in the previous PHP
version. I just asked them to turn it of and test it and it worked again.
session ids were the same and therefore...
Hope this helps..

authentification system with mysql. The registration page works well and

try to get the registered user to log in and start a session, the system
will not remember the session information past the page. For instance, this
page will not work (the one that initially is supposed to register the
session from the login form):

variable $_SESSION['login'] is called to display. It shows no memory of me
registering a session. Any variation of quotes verse apostrophes changes
nothing, so I figure that either I am blatantly screwing up the session code
(possible for I have never written any sessions before) or my system is not
supporting sessions. I have a php4 something, windows, apache 1.3.27 for my
home network server, and mysql. Any help on this problem would be greatly
appreciated.
