laravel execute command from controller code example

Example 1: run artisan command from controller

If you have simple job to do you can do it from route file. 
For example you want to clear cache. In terminal it would be php artisan 
cache:clear In route file that would be:

\Artisan::call('cache:clear');

Example 2: use php artisan command through controller

<?php
Route::get('/foo', function () {
    Artisan::queue('email:send', [
        'user' => 1, '--queue' => 'default'
    ]);
    //
});
