Hi,
I checked the session settings with phpinfo(); I get the following values:
session_save_path = /tmp
session.use_cookies = On
session.use_trans_sid = 1
I've created a folder on the same level as all the pages called
"ccb_sessions" and have CHMOD it to 777.
I have added the following snippet above session_start: <?php
session_save_path("/ccb_sessions");?>
When navigating to my test page I get the following error:
Warning: open(/ccb_sessions/sess_bbbfa69631155d4097e0b0012c857c4a, O_RDWR)
failed: No such file or directory (2) in
/home/.paco/campuscb/campuscorkboard.com/MemberAccountDetails.php on line 2
Checking with my FTP client that file is there and has CHMOD values of 777.
I've done a Google search for "No such file or directory", found a bunch of
stuff for Python, nothing for PHP.
I then closed the browser, FTP'd to the ccb_sessions folder, deleted the
sess_bbbfa69631155d4097e0b0012c857c4a file and changed the session_save_path
to session_save_page("ccb_session");. When going to the test page, it
appears to loop several times, then gives me a "The page cannot be
displayed" message.
The server is (from phpinfo())Linux gaia 2.2.20, Server API is Apache.
Other ideas?
Thanks,
James

Most things are explained well by the online manual, and you should read and
re-read the session documentation. That said, I'll also say that the
documentation on sessions is not as informative as I'd like it to be, and I
still get reports of sessions expiring before they should.
Look at the output from echo phpinfo() and check these session configuration
options:
session.cookie_lifetime -- should be 0, lasts until quitting the browser
session.use_cookies -- should be on session.use_trans_sid -- should be on
Some things aren't explained very well, like what does
"session.gc_maxlifetime" mean? The maximum time before garbage collection to
remove session data that hasn't been used? But to minimize the chance of
garbage collection on a shared server wrecking your sessions, you can
specify a directory for saving session data. Create a directory (on the same
level as your directory of publicly-viewable files if you can) and before
the 'session_start();' line, do 'session_save_path("../my_sessions_dir");'.
Also be aware that circumstances on the client side can mess with session
cookies and cause the session to be lost, like using Internet Explorer with
Entourage in Mac OS X.
