PHP 8.1.15 Released!


(PHP 4, PHP 5, PHP 7, PHP 8)

session_save_pathLit et/ou modifie le chemin de sauvegarde des sessions


session_save_path(?string $path = null): string|false

session_save_path() retourne le chemin du dossier actuellement utilisé pour sauver les données de sessions.

Liste de paramètres


Chemin des données de session. Si path est spécifié et non null, le chemin du dossier sera modifié. session_save_path() doit être appelé avant session_start().


Sur certains systèmes d'exploitation, vous aurez à choisir un chemin vers un dossier capable de gérer un grand nombre de petits fichiers efficacement. Par exemple, sous Linux, reiserfs peut se rendre plus efficace que ext2fs.

Valeurs de retour

Retourne le chemin du dossier courant utilisé pour y stocker les données, ou false si une erreur survient.


Version Description
8.0.0 path est désormais nullable.

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:


location of index.php


What I placed in index.php at line 0:

('session.save_path',realpath(dirname($_SERVER['DOCUMENT_ROOT']) . '/../session'));

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

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.:

ini_set('session.gc_probability', 1);

Otherwise, old files in '/home/' 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. :)

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.

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


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