How to create a cron in Laravel?

To create CRON in laravel follow these steps :

1) Create a command as follows:

php artisan make:command ExampleCron --command=example:cron 

within this file that was created in the app/Console/Commands/ExampleCron.php folder.

namespace App\Console\Commands;
use Illuminate\Console\Command;
use DB;
class ExampleCron extends Command
{

    protected $signature = 'example:cron';

    protected $description = 'Command E-mail';

    public function __construct()
    {
        parent::__construct();
    }
    // aqui você coloca a lógica do seu processo
    // pode utilizar todos os recursos do Laravel
    public function handle()
    {
        \DB::table('emails')->get(); // pega os e-mails
        // siga o código de sua preferencia
        // executando as funções de envio de e-mail
        $this->info('Example Cron comando rodando com êxito');
    }
}

Change the variables $signature and $description by example and in the method handle() process logic.

2) To register this command enter in the folder and file app/Console/Kernel.php and open the Kernel.php to add in array of $commands add plus command created.

namespace App\Console;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
class Kernel extends ConsoleKernel
{
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        Commands\Inspire::class,
        Commands\ExampleCron::class,
    ];
    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('inspire')->hourly();

        $schedule->command('example:cron')->daily(); // email diários
    }
}

3) Now add this line to your cron
