How to implement laravel progressbar in this example?

I know you can implement a progressbar for a console command in laravel like this:

$users = App\User::all();

$bar = $this->output->createProgressBar(count($users));

foreach ($users as $user) {
    $this->performTask($user);

    $bar->advance();
}

$bar->finish();

This works fine when you actually have your logic in the console command file itself. But how do you implement this when you have a helper file or controller that contains the foreach loop?

for example I am running a crawler with a selfwritten php artisan command:

public function handle(Crawler $crawler)
    {
        $this->info(PHP_EOL . "updating the database with beers data" . PHP_EOL);

        $crawler->startCrawler('http://ift.tt/1TM2jkh', 'product-block', '/\d+\,?\d*CL/i');
    }

My foreach loop is actually within my Crawler class here. How can I still get the progressbar to display properly?
