title: Unable to Subscribe to Redis Channel Laravel 5.2
body: <p>I am following Laravel office Redis guide but i am having some problem
  <a href="https://laravel.com/docs/5.2/redis#pubsub" rel="nofollow noreferrer">https://laravel.com/docs/5.2/redis#pubsub</a></p>
  
  <p>After creating the command when i run " -> php artisan redis:subscribe" in console i get following error</p>
  
  <pre><code>  [Symfony\Component\Console\Exception\CommandNotFoundException]  
    There are no commands defined in the "redis" namespace. 
  </code></pre>
  
  <p>I am unable to listen to Redis Chanel.</p>
  
  <p>Redis Publish Channel method is working fine. To check this.
  In console I typed "-> redis-cli" and then "subscribe mychannel"
  On refreshing browser I am getting publish data in console.</p>
  
  <p>I am unable to subscribe via Laravel.</p>
  
  <p>I also tried using wild card</p>
  
  <pre><code>Route::get('/subscribe', function()
  {
    Redis::psubscribe(['*'], function($message, $channel) {
        echo $message;
    });
  });
  </code></pre>
  
  <p>but browser keep loading and i don't get any data.
  I also tried making a method in controller</p>
  
  <pre><code>public function subscribeChannel()
  {
      $redis = Redis::Connection();
      $redis-&gt;subscribe(['channel'], function($message) {
          echo $message;
      });
  }
  </code></pre>
  
  <p>This subscribeChannel method gives me following error</p>
  
  <pre><code>ErrorException in StreamConnection.php line 390:
  strlen() expects parameter 1 to be string, array given
  </code></pre>
  
  <p>My configuration in config/database.php is folowing</p>
  
  <pre><code>'redis' =&gt; [
  
          'cluster' =&gt; false,
  
          'default' =&gt; [
              'host' =&gt; env('REDIS_HOST', 'localhost'),
              'password' =&gt; env('REDIS_PASSWORD', null),
              'port' =&gt; env('REDIS_PORT', 6379),
              'database' =&gt; 0,
              'read_write_timeout' =&gt; 0
          ],
      ],
  </code></pre>
  
  <p>Looking for help
  thanks</p>
