An Example on Redis Usage

redis_test.php

<?php

namespace Fuel\Application;

class Controller_Test extends Controller\Base {

    public function action_index()
    {
        // You can access it this way
        Redis::instance()->set('username', 'Dan');
	echo Redis::instance()->get('username');

        // Or this way
        $redis = Redis::instance();
        $redis->set('username', 'Dan');
	echo $redis->get('username');

        // Or this way (connecting to a second server).  config held in config/db.php
        $redis = Redis::instance('site2');
        $redis->set('username', 'Dan');
	echo $redis->get('username');

        // A more complex example
        $redis = Redis::instance();
        $redis->rpush('particles', 'proton');
        $redis->rpush('particles', 'electron');
        $redis->rpush('particles', 'neutron');
        $particles = $redis->lrange('particles', 0, -1);
        $particle_count = $redis->llen('particles');
        
        echo "<p>The {$particle_count} particles that make up atoms are:</p>";
        echo "<ul>";
        foreach ($particles as $particle) {
            echo "<li>{$particle}</li>";
        }
        echo "</ul>";
    }
