session_save_path — Lit et/ou modifie le chemin de sauvegarde des sessions
session_save_path() retourne le chemin du dossier actuellement utilisé pour sauver les données de sessions.
path
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().
Note:
Sur certains systèmes d'exploitation, vous aurez à choisir un chemin vers un dossier capable de gérer un grand nombre de petits fichiers efficacement.
Retourne le chemin du dossier courant utilisé pour y stocker les données, ou false si une erreur survient.

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.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. :)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.This function seems to simply return the value of session.save_path from the [Session] section of php.ini. This has an important implication: the returned value can as well look like "0;0660;/var/lib/php/sessions", which is of course no valid path.
A way to extract the path despite the possible semicolons can be something like:
$ssp = explode(';', session_save_path());
echo end($ssp);
As end takes the array by reference, it's not possible to make a real one-liner without relying on an intermediate variable.
