For more information about the SESSION time, refer to Daniel's explanation.

Regarding the SESSION time issue, Daniel explained how to use one of my pages: & nbsp; session_cache_expire (1); other pages: session_get_cookie_params (); but the result is as follows: array & nbsp; (& nbsp; [lifetime] & nbsp; = & gt; & nbsp; for more information about SESSION time, please explain
For a single page:

Session_cache_expire (1 );

For another page:
Session_get_cookie_params ();

But the result is as follows:

Array ([lifetime] => 0 [path] =>/[domain] => [secure] => [httponly] => ))

Why is life time always 0?

That is, session_cache_expire (1); does not work. I want to limit the session expiration time to 30 minutes!
