session_save_path

(PHP 4, PHP 5, PHP 7)

session_save_pathLiefert und/oder setzt den aktuellen Speicherpfad der Session

Beschreibung

session_save_path ([ string $path ] ) : string

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.

I made a folder next to the public html folder and placed these lines at the very first point in index.php

Location of session folder:

/domains/account/session

location of index.php

/domains/account/public_html/index.php

What I placed in index.php at line 0:

<?php
ini_set
('session.save_path',realpath(dirname($_SERVER['DOCUMENT_ROOT']) . '/../session'));
session_start();

This is the only solution that worked for me. Hope this helps someone.

If session.save_handler is set to files, on systems that have maximum path length limitations, when the session data file's path is too long, php may get you an error like "No such file or directory" and fails to start session, although the session-saving folder really exists on the disk.

You should:

1. Keep the session-saving folder's absolute path not too long
2. If you're with PHP 7.1+, don't set session.sid_length to a number too great, such as 255

I once got stuck with this problem on Windows and wasted hours to solve it.

Debian does not use the default garbage collector for sessions. Instead, it sets session.gc_probability to zero and it runs a cron job to clean up old session data in the default directory.

As a result, if your site sets a custom location with session_save_path() you also need to set a value for session.gc_probability, e.g.:

<?php
session_save_path
('/home/example.com/sessions');
ini_set('session.gc_probability', 1);
?>

Otherwise, old files in '/home/example.com/sessions' will never get removed!

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. :)

<?php
ini_set
('session.save_path',realpath(dirname($_SERVER['DOCUMENT_ROOT']) . '/tmp'));
ini_set('session.gc_probability', 1);
session_start();

?>

(for using above code create a tmp folder/directory in your directory)
