How to implement a delay when sending emails via Redis::throttle?

Question

Laravel

// Консольная команда
$mailingList = MailingList::find(1);
dispatch(new SendDailyNewsletter($mailingList));

//SendDailyNewsletter
namespace App\Jobs;
use App\Entity\Subscription\MailingList;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Database\Eloquent\Collection;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Redis;
use Mail;

class SendDailyNewsletter implements ShouldQueue
{
    use InteractsWithQueue, Queueable, SerializesModels;

    protected $mailing_list;

    public function __construct(MailingList $mailingList)
    {
        $this->mailing_list = $mailingList;
    }

    public function handle()
    {
        $subscriptions = DB::table('mail as m')->select(['m.email'])->where('m.id', $this->mailing_list->id)->get();

        $subscriptions->each(function ($subscription) {
            logger($subscription->email);
        });

        $subscriptions->each(function ($subscription) {
            logger('+');
            Redis::throttle('key')->allow(1)->every(5)->then(function () use ($subscription) {
                logger($subscription->email);
                //Mail::to($subscription->email)->queue(new DailyNewsletterMail($subscription->name));
            }, function () {
                return $this->release(5);
            });
        });
    }
}

I am posting via the website. For the limit, I decided to use queues and redis::throttle. Tell me why the script skips some data?

Answer 2

date("Y-m-d H:i:s", strtotime("+1 month"))

Answer 3

In the sense of just adding 1 month to some date?

$date = '2017-07-04';

$dateAt = strtotime('+1 MONTH', strtotime($date));

$newDate = date('Y-m-d', $dateAt);

echo $newDate;
