How can I run symfony 2 run command from controller

by

See official documentation on this issue for newer versions of Symfony

You don’t need services for command execution from controller and, I think, it is better to call command via run method and not via console string input, however official docs suggest you to call command via it’s alias. Also, see this answer. Tested on Symfony 2.1-2.6.

Your command class must extend ContainerAwareCommand

// Your command

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;

class MyCommand extends ContainerAwareCommand {
    // …
}


// Your controller

use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Output\NullOutput;

class SomeController extends Controller {

    // …

    public function myAction()
    {
        $command = new MyCommand();
        $command->setContainer($this->container);
        $input = new ArrayInput(array('some-param' => 10, '--some-option' => true));
        $output = new NullOutput();
        $resultCode = $command->run($input, $output);
    }
}

In most cases you don’t need BufferedOutput (from Jbm’s answer) and it is enough to check that $resultCode is 0, otherwise there was an error.
