session_save

Description

string session_save_path ( [string path] )

session_save_path() returns the path of the current directory used to save session data. If path is specified, the path to which data is saved will be changed. session_save_path() needs to be called before session_start() for that purpose.

注: On some operating systems, you may want to specify a path on a filesystem that handles lots of small files efficiently. For example, on Linux, reiserfs may provide better performance than ext2fs.

See also the session.save_path configuration directive.

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\\"
