Location for session files in Apache/PHP

In Apache, the location for session files is determined by the session.save_path configuration directive in your php.ini file. This directive specifies the path on the server where session files should be stored.

For example, if you have the following line in your php.ini file:

session.save_path = "/var/lib/php/sessions"

then Apache will store session files in the /var/lib/php/sessions directory on the server.

You can also specify a different location for session files by calling the session_save_path() function in your PHP code. This function sets the current session save path for the current request. For example:

session_save_path('/tmp');

This will set the session save path to /tmp for the current request, and any sessions created during this request will be stored in the /tmp directory.

It's worth noting that the session.save_path directive and the session_save_path() function are both server-side configurations, and they have no effect on how sessions are stored or managed in the client's browser.
