What keeps a php session alive? -


are sessions kept alive each time access page session_start(); or other pages keep alive too?

example (with 30 minute timeout):

1

user accesses page session_start();
25 mins later access session_start();
page session stays alive

2

user accesses page session_start();
25 mins later access non-session_start(); page
session stays alive

is 2 true ?

there session cookie set in browser whenever access page has session_start(). cookie name phpsessid if website using php(although name can changed). session cookie contains session id helps browser maintain session server.

you can check manually browsing website has session , delete browser cookies, session lost.

in case both 1 & 2 correct.

2 correct because user has accessed page has session_start() , session id set next 30 mins , present if accesse page not have session.

note: page visiting if contains session_destroy(), session destroyed.
