Get response from Artisan call

Question

When I run in terminal php artisan migrate this results in \'Nothing to migrate\' when indeed there is nothing to migrate.

When I use Artisan::call(\'

Answer 1

Yes, it's possible. To get the output of a built-in artisan command from inside a custom command, pass the OutputStream from your command into the Artisan::call. Example:

class MyCommand extends \Illuminate\Console\Command
{
    public function fire()
    {
        \Artisan::call('optimize', [], $this->getOutput());
    }
}

Answer 2

I'm able to get the output of Artisan::call() with the via the following:

use Symfony\Component\Console\Output\StreamOutput;

$stream = fopen("php://output", "w");
Artisan::call("migrate", array(), new StreamOutput($stream));

var_dump($stream);

The return result of all commands is defined in the class Symfony\Component\Console\Command\Command, method run:

return is_numeric($statusCode) ? (int) $statusCode : 0;

The $statusCode variable is set by calling the command's execute method, which in artisan's case is defined in the class Illuminate\Console\Command:

protected function execute(InputInterface $input, OutputInterface $output)
{
    return $this->fire();
}

The result of the fire method is left up to the individual commands, in the case of php artisan migrate command, nothing is returned from the method so the $statusCode is null (which is why you get the 0 returned from Symfony\Component\Console\Command\Command::run method)

If you want to get a response back from a custom command, just return an integer back from your fire method and it will bubble back up into the $statusCode. You can use that to programmatically switch against different results of your custom command.

If you specifically want to get the result from the artisan:migrate command, then I don't think there's much you can do to change the return value besides wrapping the command in your own custom command that calls it.

Late but might be of use to someone searching for the use case.

Let me add how i did it in my tests to print the results to console. my problem was printing output while tests are running migrations. i was using modules and wanted to see the results of the migration process.

$this->artisan('module:migrate');
//same as running php artisan module:migrate or
// $this->app['Illuminate\Contracts\Console\Kernel']->call('module:migrate');

echo $this->app['Illuminate\Contracts\Console\Kernel']->output();

Answer 5

When the Artisan command output you want is issuing an echo.

You can access this type of output with ob_start and ob_get_clean.

For example, if your command echos JSON.

Artisan::command('myecho:command', function () {

    echo json_encode(config('myconfig'), true);

})->describe('outputs json');

Then you can access the JSON output by wrapping the command call in a buffer:

\ob_start();
\Artisan::call('myecho:command');
$output = \ob_get_clean();

var_dump($output);

Maybe this will save some time to someone in the future, for me worked a mix of 2 answers:

use Symfony\Component\Console\Output\StreamOutput;

$stream = fopen("php://output", "w");
Artisan::call('migrate', [
    '--path' => 'database/migrations/customer',
    '--force' => true,
    '--database' => $connectionName
], new StreamOutput($stream));

$callResponse = ob_get_clean();

StreamOutput helps to put the response in buffer and ob functions to get the response.
