Parse PHP Session in Javascript

Question

I have recently gone into extending my site using node.js and have come to realisation I need a session handler for my PHP sessions. Now everything was cool and dandy and node.j

Answer 1

Just to reply with the way I've found: force PHP to use JSON instead :

Use the class below, with session_set_save_handler to store data as JSON and let PHP still using his own system. Link this class using this function at the beginning of each script you use session : http://php.net/manual/ru/function.session-set-save-handler.php

PS : here the class use memcache to store JSON resulting object, on Node.JS, use a memcache object, and retrieve like this :

• get the PHPSESSID from cookies
• use that characters string to bring a key from memcached with "sessions/id" where id is the key and session just the string (see class below).

Now you should have only JSON in memcache, so it's becoming a simple game with Node.JS to work with.

PS : of course you can work with/improve this, you can also use this not only with memcache (a db for example)

addServer('localhost', 11211);
}

    public function __destruct(){
            session_write_close();
            self::$memcache->close();
            self::$memcache = null;
    }

    public static function open(){
            self::$lifetime = ini_get('session.gc_maxlifetime');
            return true;
    }

    public static function read($id){
            $tmp = $_SESSION;
            $_SESSION = json_decode(self::$memcache->get("sessions/{$id}"), true);
            $new_data = session_encode();
            $_SESSION = $tmp;
            return $new_data;
    }

    public static function write($id, $data){
            $tmp = $_SESSION;
            session_decode($data);
            $new_data = $_SESSION;
            $_SESSION = $tmp;
            return self::$memcache->set("sessions/{$id}", json_encode($new_data), 0, self::$lifetime);
    }

    public static function destroy($id){
            return self::$memcache->delete("sessions/{$id}");
    }

    public static function gc(){
            return true;
    }

    public static function close(){
            return true;
    }
}
