session_register
Session on clustered web servers !
We had problem in PHP session handling with 2 web server cluster. Problem was one servers session data was not available in other server.
So I made a simple configuration in both server php.ini file. Changed session.save_path default value to shared folder on both servers (/mnt/session/).
It works for me. :)
session_save_path
(PHP 4, PHP 5)
session_save_path — Liefert und/oder setzt den aktuellen Speicherpfad der Session
Beschreibung
string session_save_path
([ string $path
] )
session_save_path() gibt den Pfad des aktuellen Verzeichnisses zurück, das zum Speichern der Session-Daten verwendet wird.
Parameter-Liste
- path
-
Der Pfad der Session-Daten. Sofern angegeben, wird der Pfad, unter dem Daten gespeichert werden, entsprechend geändert. Zu diesem Zweck muss session_save_path() vor session_start() aufgerufen werden.
Hinweis: Unter manchen Betriebssystemen, wollen Sie vielleicht einen Pfad auf einem Dateisystem angeben, das sehr viele kleine Dateien effizient behandelt. Unter Linux, zum Beispiel, bietet reiserfs eventuell eine bessere Performance als ext2fs.
Rückgabewerte
Gibt den Pfad des aktuellen Verzeichnisses zurück, das zum Speichern der Session-Daten verwendet wird.

Note that you shouldn't use session_save_path() directly for performing file operations.
It returns the configuration option, not the directory.
As stated in /manual/en/ref.session.php#ini.session.save-path there can be a numeric argument separated with a semicolon in front of the "real" path.
I used the following code to get rid of it:
<?php
$sessionpath = session_save_path();
if (strpos ($sessionpath, ";") !== FALSE)
$sessionpath = substr ($sessionpath, strpos ($sessionpath, ";")+1);
?>
Doesn't allow ; to appear in the directory names, but hey.

sometime you need to change session.save_path because server system distributed more then one machine and you can not reach php.ini file example sourceforge.net. Then you can do that with .htaccess file which is kind of configuration file for Apache under one directory. anyway I added
php_value session.save_path /home/groups/f/f4/f4l/tmp/
now my sessions work very well I hope :)

This is an absolute must if you have an important login on a shared server. Without it, other users of the server can do the following to bypass login:
* Visit login page, browse through cookies and grab the session id.
* Create a PHP script on their account that grabs and sets session variables for a given session id.
* Read and change any values for that session id (for example passwords or session keys), and therefore gain access to the protected area.
All users on web hosting should choose an dir below the HTTP directory struct, but within their user area to store the session files.

dont forget: if you use session_save_path on the page, that registers a variable, you have also to use session_save_path on all the pages, where you access the session-variable. under win32 you can use the double \\ to specify eg "c:\\temp\\"
