Share sessions between php and node

Is there an recent guide (or example code) to using node, express, and redis/predis to share PHPSESSID?

I've found several tutorials 1-2 years old and they are all either using old versions express or not using express.

Express cookie parser is also deprecated.

https://simplapi.wordpress.com/2012/04/13/php-and-node-js-session-share-redi/

NodeJS + ExpressJS + RedisStore Session is undefined

It would be great if someone could post some more recent code...

EDIT - extract of node server code so far:

var express = require('express'),
app = express(),
server = require('http').createServer(app),
io = require('socket.io').listen(server),
redis   = require('redis'),
client  = redis.createClient();    

var session = require('express-session'),
RedisStore = require('connect-redis')(session);

app.get('/', function(req, res) {
    res.sendfile('/');
});

app.use(
    session({
            name: 'PHPSESSID'
    store: new RedisStore({
        prefix: 'PHPSESSID',
        port: 6379
    })
})
);

io.sockets.on('connection', function (socket) {

    app.use(function(req, res, next) {
        console.log(req.session);
    });

For node (and Express 4.x):

Start with the example from express-session, but use connect-redis as your session store instead.

Example code:

var express = require('express'),
    app = express(),
    cookieParser = require('cookie-parser'),
    session = require('express-session'),
    RedisStore = require('connect-redis')(session);

app.use(express.static(__dirname + '/public'));
app.use(function(req, res, next) {
  if (req.url.indexOf('favicon') > -1)
    return res.send(404);
  next();
});
app.use(cookieParser());
app.use(session({
  store: new RedisStore({
    // this is the default prefix used by redis-session-php
    prefix: 'session:php:'
  }),
  // use the default PHP session cookie name
  name: 'PHPSESSID',
  secret: 'node.js rules'
}));
app.use(function(req, res, next) {
  req.session.nodejs = 'Hello from node.js!';
  res.send(JSON.stringify(req.session, null, '  '));
});

app.listen(8080);

For PHP:

Use a redis session handler like redis-session-php.

Example code:

<?php

// from https://github.com/TheDeveloper/redis-session-php
require('redis-session-php/redis-session.php');
RedisSession::start();

$_SESSION["php"] = "Hello from PHP";

// `cookie` is needed by express-session to store information
// about the session cookie
if (!isset($_SESSION["cookie"]))
  $_SESSION["cookie"] = array();

var_dump($_SESSION);

?>

Note: Make sure you use the same prefix(connect-redis)/REDIS_SESSION_PREFIX(redis-session-php) (connect-redis uses 'sess:' and redis-session-php uses 'session:php:' by default) and ttl(connect-redis)/session.gc_maxlifetime(PHP) (and same database if you are using a redis database other than the default) for both redis-session-php and connect-redis.
