I have the same problem.
System:
Linux 2.6.26-2-686 #1 SMP Sat Jun 11 14:54:10 UTC 2011 i686
PHP 5.3.3-7+squeeze1 with Suhosin-Patch (cli) (built: Mar 18 2011 17:22:52)

Problem:
One PHP script creates a session (474 bytes), which I want to read with another
PHP script.
The second script starts like this:
<?php
session_start();
var_dump( session_name() . "=" . $_COOKIE['PHPSESSID'], "<br>\n" );
var_dump($_SESSION, "<br>\n");
...
The problem is, that when I start second script, the 474 bytes of the session
is emptied to 0 bytes.
The the domain of first and second script are different, but they are on the
same virtual hosted server, and they use the same session path: /var/lib/php5
/etc/php5/apache2/php.ini session settings are:
[Session]
session.save_handler = files
session.save_path = /var/lib/php5
session.use_cookies = 1
session.name = PHPSESSID
session.auto_start = 0
session.cookie_lifetime = 0
session.cookie_path = /
session.cookie_domain =
session.cookie_httponly =
session.serialize_handler = php
session.gc_divisor = 100
session.gc_maxlifetime = 1440
session.bug_compat_42 = 1
session.bug_compat_warn = 1
session.referer_check =
session.entropy_length = 0
session.entropy_file =
session.cache_limiter = nocache
session.cache_expire = 180
session.use_trans_sid = 0
session.hash_function = 0
session.hash_bits_per_character = 4
Any ideas?

Hi there,
I was having the same problem with PHP creating session files with 0Kb.
I solved putting the <? session_start();?> on the first line of the php file.
After this it works like a charm.
Hope it helps somebody.

Running on default XAMPP installation, with the
session.save_path = "C:\xampplite\tmp"
When I set the apache document root to be:
<Directory "C:/xampplite/htdocs">
And then run a file with contents:
<?PHP session_start(); ?>
There is a session file created. Ie, normal operation.
When I set the apache document root to be:
<Directory "S:/htdocs">
And then run THE SAME file with contents:
<?PHP session_start(); ?>
A 0KB session file is created. Ie, it is empty, and I cannot access session
variables.
Please help.

Session files are shared via NFSv4, if it is important.

Hello, I have theis session problem, tried everything on this page not still
wont work. Is anyone else having the problem still??
I have 2 servers, one it works fine on and the other it fails, they use the
same settings, and have tried differant versions, yet it still fails on the 2nd
server.
Ho many people here are running it on a server with a " _ " in the computer
name? that to me seems the only thing differant between the computers with my
setup.
