How can I run symfony 2 run command from controller

Question

I\'m wondering how can I run Symfony 2 command from browser query or from controller.

Its because I don\'t have any possibility on hosting to run it

If you have to pass arguments (and/or options), then in v2.0.12 (and may be true for later versions), you need to specify InputDefinition first before instantiating an input object.

use // you will need the following
    Symfony\Component\Console\Input\InputOption,
    Symfony\Component\Console\Input\InputArgument,
    Symfony\Component\Console\Input\InputDefinition,
    Symfony\Component\Console\Input\ArgvInput,
    Symfony\Component\Console\Output\NullOutput;


// tell symfony what to expect in the input
$inputDefinition = new InputDefinition(array(
    new InputArgument('myArg1', InputArgument::REQUIRED),
    new InputArgument('myArg2', InputArgument::REQUIRED),
    new InputOption('debug', '0', InputOption::VALUE_OPTIONAL),
));


// then pass the values for arguments to constructor, however make sure 
// first param is dummy value (there is an array_shift() in ArgvInput's constructor)
$input = new ArgvInput(
                        array(
                                'dummySoInputValidates' => 'dummy', 
                                'myArg2' => 'myValue1', 
                                'myArg2' => 'myValue2'), 
                        $inputDefinition);
$output = new NullOutput();

As a side note, if you are using if you are using getContainer() in your command, then the following function may be handy for your command.php:

/**
 * Inject a dependency injection container, this is used when using the 
 * command as a service
 * 
 */
function setContainer(\Symfony\Component\DependencyInjection\ContainerInterface $container = null)
{
    $this->container = $container;
}

/**
 * Since we are using command as a service, getContainer() is not available
 * hence we need to pass the container (via services.yml) and use this function to switch
 * between conatiners..
 *
 */
public function getcontainer()
{
    if (is_object($this->container))
        return $this->container;

    return parent::getcontainer();
}
