How to use Session Save Path in PHP

PHP supports session_save_path() function from version 4

What is session_save_path?

session_save_path() sets or returns the path where data for the current session is saved.If you pass no arguments into a function, it returns the current directory where session files are stored.

To Get default Session Path

By default, PHP stores session data in files and files are stored in the /tmp directory of your server.Each session is stored in its own file.

session data file stored in /tmp is like sess_1f1b1bdb809709f09f45b049998f25dc43745a67.

To Set Session Save Path in php.ini

session_save_path function returns the current session save path.If session_save_path() function returns null,then session.save_path is commented in your php.ini file.

So Uncomment session.save_path in a php.ini and set path in it.Let’s have a look

To Change Session Save Path

To change the default path of stored session, you can use same function session_save_path( ) but with the parameter which is the path of the new directory where you session files will be stored but you need to call this function before accessing any session variables like session_start();

BENEFIT

This simple change can greatly improve the security of the sessions stored in files because we are storing it in custom directory for application so it is Securing Session Storage
