According to the PHP docs (http://php.net/manual/en/session.configuration.php#ini.session.cookie-domain), session.cookie_domain's default value is set to the domain that generated the cookie.
Default is none at all meaning the host name of the server which generated the cookie according to cookies specification Ok, so how do I set session.cookie_domain to use the cookie on subdomains and on the original domain which generated the cookie without having to specifically specify it? I'm looking for something like session.cookie_domain = .[$SERVER_NAME] Instead of having to specifically state which domain it is like countless other examples have used: session.cookie_domain = .example.com Since my server will be hosting multiple domains, is there a way to get this setting to be set dynamically based on the host that generated the cookie to use the cookie on subdomains and the domain itself in the php.ini configuration? PHP Sessions across sub domains appears to be similar to what I'm after, but I don't want to have to set it in the script. I want to set it in the php.ini configuration so that cookies issued from any of my hosted domains will also be used and valid for their corresponding subdomains. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
