How to run Drupal console command from code?

Question

I have found a lot of documentation on how to run Drush commands from code, but I'm specifically looking on how to run a Drupal Console command from code.

I have some experience in Symfony and I know how to run a Symfony command from code. Since a Drupal console command extends on Symfony command, I thought this should be rather easy. Simply following this tutorial doesn't amount to anything though.

I am trying to run a command in a hook_cron() implementation in a custom module.

Answer 1

Try using the PHP functions exec() or shell_exec().

Answer 2

Run shell commands via the Process class available in the Symfony framework.

From the Symfony docs:

use Symfony\Component\Process\Process;
use Symfony\Component\Process\Exception\ProcessFailedException;

$process = new Process('ls -lsa');
$process->run();

// executes after the command finishes
if (!$process->isSuccessful()) {
    throw new ProcessFailedException($process);
}

echo $process->getOutput();

The component takes care of the subtle differences between the different platforms when executing the command.

Replace the ls -lsa command in the Process() constructor with your Drupal console command.
