session_save_path()

(PHP 4, PHP 5, PHP 7)

读取/设置当前会话的保存路径

说明

session_save_path()返回当前会话的保存路径。

参数

指定会话数据保存的路径。必须在调用session_start()函数之前调用session_save_path()函数。

Note:

在某些操作系统上，建议使用可以高效处理大量小尺寸文件的文件系统上的路径来保存会话数据。例如，在 Linux 平台上，对于会话数据保存的工作而言，reiserfs 文件系统会比 ext2fs 文件系统能够提供更好的性能。

返回值

返回保存会话数据的路径。

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:

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. :)

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