What are the causes that cause a php Session to expire?

Question

In php, Sessions are useful for temporarily holding data. But mine are expiring very fast (in less than 15 minutes) and I still can’t figure out why. Man Session.cache_expire, according to phpinfo() is set to 240.

Thanks in advance.

Answer 1

You have to change the parameter session.cookie_lifetime more information on PHP website

Update:

Try to increase as well session.gc_maxlifetime ex.

ini_set('session.gc_maxlifetime', 3600);
session_set_cookie_params(3600);
session_start();
