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) Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies with Suhosin v0.9.32.1, Copyright (c) 2007-2010, by SektionEins GmbH 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?

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.

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.

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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
