Question 67
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?
A. PHP will delete the associated session file when session_destroy() is
called from within a script.
B. When the function session_cleanup() is called, PHP will iterate over all
session files, and delete them if they exceeded the session timeout limit.
C. When the function session_start() is called, PHP will iterate over all
session files, and delete them if they exceeded the session timeout limit.
D. 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.
E. Session files are never removed from the filesystem, you need to use an automated
script (such as a cronjob) to do this.
