Get response of custom artisan command in controller - laravel

Question

I have created custom artisan command and trying to get response of it.
Here is the handle method of custom artisan command.
/**
* Execute the console command.
*
* #return string
*/
public function handle()
{
return 'Hello world';
}
Calling command from the controller
$result = Artisan::output('app:custom-command');
dd($result); // 0
dd(Artisan::output()); // ''
Expecting 'Hello world' in the controller.
Please note I want response not the output
i.e Not the output of $this->info('test.');

Answer 1

Commands don't return spesific variable they return an exit code.
if you get "hello world" from command;
command:
$this->info('Hello World');
controller:
Artisan::call('app:custom-command');
return Artisan::output();

First, please check these answers here:

Just to give you an insight, here a small thing you can do:
You can pass a variable by reference to the constructor of the Command class
As an example:
// File => UserController
$commandInstance = new DemoCommand($output);
$commandInstance->hanlde(); // Calling the related method manually
// Then in the DemoCommand Class #constructur method
public function __construct(&$output){
$this->output = $output;
}
// File => DemoCommand #handle Method
$result = ['a', 'b' ]; // ...
$commandInstance->setOutput($result);
You can also use session, Redis to save the data in memory and read it from the related class you need or store the output into a file or database...
