Show progress of a file download inside Symfony 2.3 console #howto

YourCommand.php

<?php

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $progress = $this->getHelperSet()->get('progress');
        $ctx = stream_context_create(array(), array('notification' => function ($notification_code, $severity, $message, $message_code, $bytes_transferred, $bytes_max) use ($output, $progress) {
            switch ($notification_code) {
                case STREAM_NOTIFY_FILE_SIZE_IS:
                    $progress->start($output, $bytes_max);
                    break;
                case STREAM_NOTIFY_PROGRESS:
                    $progress->setCurrent($bytes_transferred);
                    break;
            }
        }));
        $file = file_get_contents($url, false, $ctx);
        $progress->finish();
    }

Indeed, that would be a good addition to the docs.

👍 thank you for this.

I had to change $progress->start($output, $bytes_max); to $progress->start($bytes_max); on last symfony/console version though (2.6.4) .
