Calling a console command from a controller using the Process component in Symfony2

Question

I am attempting to call a console command from a controller using the Process component in Symfony2 to have it run in the background, however all it does is hang and end up at a white screen. This is an example of what fails:

$process = new Process('php app/console list');
$process->setWorkingDirectory($this->get('kernel')->getRootDir().'/../');
$process->run();
print $process->getOutput();

I have tried interchanging $process->run() with $process->start() and it still doesn't work.

you need to start a new operating system process with the exec command — jack, May 06 '15 at 18:27
`process->start() ` runs process asynchronously and works for me. http://symfony.com/doc/current/components/process.html#running-processes-asynchronously — Aurelijus Rozenas, Jul 04 '16 at 12:38

Checkout AsyncServiceCallBundle, it allows you to execute your application service's methods in background without having to wait until they are finished. Just use it like this:

$this->get('krlove.async')->call('service_id', 'method', [$arg1, $arg2, $arg3]);

It uses this approach to make such calls asynchronous.
