session_save_pathПолучает и/или устанавливает путь сохранения сессии


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

session_save_path() возвращает путь текущей директории, которая используется для сохранения данных сессии.

Список параметров


Путь для данных сессии. Если указан и не равен null, то путь, куда сохраняются данные, будет изменён. Для этой цели session_save_path() следует вызывать перед session_start().


В некоторых операционных системах вы можете указать путь в файловой системе, которая эффективно обрабатывает большое число небольших файлов. Например, в Linux файловая система reiserfs может обеспечить лучшую производительность, чем ext2fs.

Возвращаемые значения

Возвращает путь текущей директории, используемой для хранения данных сессии или false в случае возникновения ошибки.

Список изменений

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/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.

('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)
