When using the default session handler files for using sessions, PHP stores session information on the harddrive of the webserver. When are those session files cleaned up?

PHP will delete the associated session file when session_destroy() is called from within a script.

When the function session_cleanup() is called, PHP will iterate over all session files, and delete them if they exceeded the session timeout limit.

When the function session_start() is called, PHP will iterate over all session files, and delete them if they exceeded the session timeout limit.

When the function session_start() is called, PHP will sometimes iterate over all session files, and delete them if they exceeded the session timeout limit.

Session files are never removed from the filesystem, you need to use an automated script (such as a cronjob) to do this.
