Symfony3 Command - pcntl doesn't works

Question

I want to stop executing my command from controller action so I tried to use pcntl to achieve this.

This is my code(Command):

protected $should_stop = false;

protected function execute(InputInterface $input, OutputInterface $output)
{
    pcntl_signal(SIGHUP, [$this, 'stopCommand']);

    foreach($something as $row) {
       pcntl_signal_dispatch();

       if($this->should_stop === true) {
          break;
       }
       ...
    }
}

protected function stopCommand()
{
    $this->should_stop = true;
}

But when I run my command it display error:

  [Symfony\Component\Debug\Exception\UndefinedFunctionException]                   
  Attempted to call function "pcntl_signal" from namespace "AppBundle\Command".

I have no idea how to fix it, could you guys help? Also if you have any other good method how to stop executing symfony command from the controller action it would be nice if you could post the solution here.

Not a duplicate, but pretty related: https://stackoverflow.com/questions/33036773/how-to-enable-pcntl-in-php-while-using-a-framework-like-symfony2 Most probably you do not have PCNTL compiled into CLI — Jovan Perovic, Dec 22 '17 at 12:10
Guess you should check in your app_dev.php/_profiler/phpinfo if the functions are enabled. Or either restart your apache. — Tim Zwinkels, Dec 22 '17 at 15:42
