Thanks! Awesome script!

Just passing by,

I've come up with a shorter version:

<?php
# ./bin/dump-container.php
use Symfony\Component\DependencyInjection\Dumper\GraphvizDumper;

require __DIR__.'/../vendor/autoload.php';

$kernel = new AppKernel('dev', true);
$getContainer = function() {
    $this->initializeBundles();
    $container = $this->buildContainer();
    $container->compile();

    return $container;
};
$container = $getContainer->call($kernel);
$dumper = new GraphvizDumper($container);

echo $dumper->dump([
    'graph' => [
        'rankdir' => 'RL',
    ]
]);

Thanks
