PHP sessions default timeout

Q: would a user eventually be “logged out” after some time of inactivity?
A: It depends on the server configuration or the relevant directives (session.gc_maxlifetime) in php.ini. Typically the default is 24 minutes (1440 seconds), but your webhost may have altered the default to something else.
