It should be noted that this gets the session cookie ini file parameters, not the parameters from the cookie itself.
ie. if you set the cookie lifetime using session_set_cookie_params(12345) and then try to use session_get_cookie_params, you will not get back 12345. Instead, you will get the lifetime set in the ini file.

This function is quite handy when it comes to expiring session cookies... since Session cookies don't automatically get destroyed (see the session_destroy page).
For instance, here's what I plan to use to expire session cookies:
$CookieInfo = session_get_cookie_params();
if ( (empty($CookieInfo['domain'])) && (empty($CookieInfo['secure'])) ) {
setcookie(session_name(), '', time()-3600, $CookieInfo['path']);
} elseif (empty($CookieInfo['secure'])) {
setcookie(session_name(), '', time()-3600, $CookieInfo['path'], $CookieInfo['domain']);
} else {
setcookie(session_name(), '', time()-3600, $CookieInfo['path'], $CookieInfo['domain'], $CookieInfo['secure']);
}
session_destroy();
It doesn't check to see if the path part of the session cookie is set because the defaults in php.ini have this set already, unlike domain and secure.

Try also
* INI_Get('session.cookie_lifetime')
* INI_Get('session.cookie_path')
* INI_Get('session.cookie_domain')
* INI_Get('session.cookie_secure')
* INI_Get('session.cookie_httponly')
separately instead of session_Get_Cookie_Params().
Additionally there is a "bug" - session.cookie_lifetime is mentioned twice in the description.
