You can use memcached as your session storage handler in PHP. Memcached is a simple key value store that can be accessed via TCP; there is a memcached module available for Node.js.

PHP stores the session in memcached by using the session id as the key. The session data (value) stored in memcached is a serialized PHP object, with a slight twist. You can read more about this unusual serialization at the SO question "Parse PHP Session in Javascript". Luckily though, there is already an NPM module out there: php-unserialize.

Now for the How-To.
