Share sessions between php and node

Question

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

Answer 1

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:

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.
