php subdomain session sharing

Question

I need to share a session between two subdomains.

I have these domains:

http://example.com
https://secure.example.com

And I tried session sharing with this way:

<?php ini_set("session.cookie_domain", ".example.com"); session_start(); ?>

And this also

<?php session_set_cookie_params ( 0,"/" ,".example.com"); session_start(); ?>

But both seems not working!

How can I make it works?

Sorry for bad English

Answer 1

I don't think sessions are shared across sub-domains. Instead assign the value of the session to a cookie. The cookies are shared.

setcookie("TestCookie", $value, time()+3600);

get the value of the cookie by using this:

$_COOKIE['TestCookie'];

Answer 2

Solved.

I created .htaccess file with this content:

php_value session.cookie_domain ".example.com"
