我如何使用$ session_get_cookie_params？

Question

http://www.php.net/manual/en/function.session-get-cookie-params.php

How do I use this session_get_cookie_params()? I've tried

$session_get_cookie_params['session.cookie_lifetime'] does nothing

although

INI_Get('session.cookie_lifetime') shows 0

var_dump($session_get_cookie_params) gives NULL

Should I set before I try to get them?

Answer 1

session_get_cookie_params is a function, not a variable. You use it like this:

$cookie_params = session_get_cookie_params();
echo $cookie_params['lifetime'];
