Class Memcache not found - Session tutorial issue

[Bret Hudson]

I'm having issues with the following PHP code, which is derived from the sessions tutorial on the Ratchet site:

<?php

use Ratchet\App;

use Ratchet\Server\IoServer;

use Ratchet\Http\HttpServer;

use Ratchet\WebSocket\WsServer;

use Ratchet\Session\SessionProvider;

use Symfony\Component\HttpFoundation\Session\Storage\Handler;

use Symfony\Component\HttpFoundation\Session\Storage\Handler\MemcacheSessionHandler;

use TNTWS\UserConnector;

require dirname(__DIR__) . '/vendor/autoload.php';

$memcache = new Memcache;

$memcache->connect('localhost', 11211);

$server = IoServer::factory(

new HttpServer(

new WsServer(

new SessionProvider(

new UserConnector(),

new MemcacheSessionHandler($memcache)

)

)

),

8080

);

$server->run();

?>

I continue to get "Class 'Memcache' not found on line 13". My composer.json is as follows:

{

"autoload": {

"psr-0": {

"TNTWS": ""

}

},

"require": {

"symfony/http-foundation": "2.6.*",

"cboden/ratchet": "0.3.*"

}

}

I've searched for nearly an hour with no luck on finding a solution. Hopefully someone can point out my mistake or find out what's going on. Thanks!

Hi, you have to install memcache like this "sudo apt-get install php5-memcache"
