Predis configuration in Laravel 5.2 - configuration

Question

I am confused about the Predis setup (PHP client for Redis) in this case in a Laravel 5.2 project.
The documentation says you need to autoload it into composer to use it in the entire app without loading it on each page...
HOW? WHERE? WHAT? do I need to add or write to do this? I can't seem to figure it out as I know very little about installation en server configuration..
This is what I mean. This needs to go somewhere I assume
require 'Predis/Autoloader.php';
Predis\Autoloader::register();
Thx

Answer 1

Another method
Download predis package from https://github.com/nrk/predis
Extract it
Copy the contents of folder into Laravel/vendor/predis/predis. Then folder structure will be
In Controller
class WelcomeController extends Controller
{
public function index()
{
$client = new \Predis\Client([
'scheme' => 'tcp',
'host' => '127.0.0.1',
'port' => 6379
]);
$client->set('foo', 'bar');
return $value = $client->get('foo');
}
}
If redis is installed in your system, it will return value of 'bar'

Please, read documentation careful:
Autoloading is handled automatically when dependencies are managed through Composer, but it is also possible to leverage its own autoloader in projects or scripts not having any autoload facility:
// Prepend a base path if Predis is not available in your "include_path".
require 'Predis/Autoloader.php';
Predis\Autoloader::register();
By default Laravel uses Composer to install dependencies, so you do not need to do anything special. Just add predis/predis as usual to your deps in composer.json. Read more using of composer here.
