php sessions -- unix vs. windows

Anon

hello,

i have a local windows machine running php and mysql. I have code that uses session and it works great on my local.

I moved it to my hosting provider (unix) and the code does not work now.

?????

i am using the same php.ini file and running the same code.

I did change the save_path variable and that works.

I think the problem is this::::

I can see the session file but it is empty on the unix server.
I can see the session file on my local windows machine and it has the variables in it.

WHAT is the difference between unix and windows... as to why the session file is not getting populated?

THANKS

It's not about windows and unix.. check your and provider php versions and php.ini for differences (use phpinfo()😉
$HTTP_SESSION_VARS was not guaranteed, reflection of session to global vars is not guaranteed, and where was problems with $HTTP_SESSION_VARS[]=.

THis is the only code I use:

this part---

if (!isset($SESSION['ses_visitorid'])) {
$SESSION['ses_visitorid'] = $newvisitorid;;

and this part---

$id = $_SESSION['ses_visitorid'];

what is happening is the session file is being created BUT it is empty..

I have not check the differences between phpinfo yet, BUT should they be the same if I am using the same php.ini???

thanks

For example version of PHP on your provider has no _SESSION at all. Because this is the new feature. Use HTTP_SESSION_VARS instead.

argGGGGGGGGGGGGGG!!!!

local php version is 4.1.1
provider php version is 4.0.6

so I changed _session to http_session_vars,
but now I have the same problem on my local.

It writes the session file but it is empty. this is my code

session_start();

// only insert one record per session per visitor
if (!isset($HTTP_SESSION_VARS['ses_visitorid'])) {

$HTTP_SESSION_VARS['ses_visitorid'] = $newvisitorid;
}

thanks!!

All session variables must be registered by session_register() before using and before any output (or you will have problem in the case of non-buffered output).
