16. Awesome!
Let's ditch PHP!
Or use the right tool for the right job...
17. Reasons to use PHP still
● PHP works
● Familiarity, maturity
● Existing code in PHP
● Node still in its infancy (created in 2009)
○ Not as many frameworks, libraries
○ May have to write more code for some basic things
○ APIs may change, not version 1.0 yet
18. Oh yeah, the integrating part...
Memcache/redis/
something else
Session data Session data
PHP Node
19. However...
Sessions are serialized by PHP:
not|a:2:{i:0;s:4:"easy";i:1;a:1:{s:2:"to";s:5:"parse";}}
Easier to parse JSON in Node.js:
{"this": {"is": "easier"}}
20. Use my session save handler...
On Packagist: lboynton/memcached-json-
session-save-handler
Or msgpack: https://github.
com/msgpack/msgpack-php
● ini_set('session.serialize_handler', 'msgpack')
21. Quick example... (PHP)
// create connection to memcached
$memcached = new Memcached();
$memcached->addServer('localhost', 11211);
// register handler (PHP 5.3 compatible)
$handler = new LboySessionSaveHandler($memcached);
session_set_save_handler(
array($handler, 'open'),
array($handler, 'close'),
array($handler, 'read'),
array($handler, 'write'),
array($handler, 'destroy'),
array($handler, 'gc')
);
register_shutdown_function('session_write_close');
session_start();
// start using the session
$_SESSION['serialisation'] = 'this should be in json';
22. Quick example... (Node.js)
1. Get session ID from cookie
2. Get session data out of memcached
3. Use session data to identify client and send
relevant info to their browser
See demo app...
23. Conclusion...
● Using Node is fun...
● Good way to add real-time functionality to
existing website
● Can be used for much more
