sbooker / persistent-sequences example snippets


// Генерируем следующий уникальный ID для нового пользователя
$nextUserId = (int)$sequenceGenerator->next('users_pk', new Algorithm\Increment(1));
$user = new User($nextUserId, /* ... */);
$transactionManager->persist($user);

// Получаем следующий номер для счета
$nextInvoiceNumber = $sequenceGenerator->next('invoices', new InvoiceAlgorithm());
// $nextInvoiceNumber будет "INV-2023-0001"


// bootstrap.php или ваш DI-контейнер

/** @var Sbooker\TransactionManager\TransactionManager $transactionManager */
$sequenceGenerator = new Sbooker\PersistentSequences\SequenceGenerator($transactionManager);


// src/Infrastructure/Persistence/DoctrineSequenceReadStorage.php
use Doctrine\ORM\EntityManagerInterface;
use Sbooker\PersistentSequences\Sequence;
use Sbooker\PersistentSequences\SequenceReadStorage;

final class DoctrineSequenceReadStorage implements SequenceReadStorage { /* ... */ }


// bootstrap.php или ваш DI-контейнер
/** @var DoctrineSequenceReadStorage $readStorage */
$sequenceReader = new Sbooker\PersistentSequences\SequenceReader($readStorage);

// В вашем коде:
$lastUserId = $sequenceReader->last('users_pk');


// src/Sequences/InvoiceAlgorithm.php
use Sbooker\PersistentSequences\Algorithm;

final class InvoiceAlgorithm implements Algorithm
{
    public function first(): string
    {
        return "INV-2023-0000";
    }

    public function next(string $currentValue): string
    {
        // Простая (но не идеальная) реализация для примера
        [$prefix, $year, $number] = explode('-', $currentValue);
        $nextNumber = str_pad((string)((int)$number + 1), 4, '0', STR_PAD_LEFT);

        return "$prefix-$year-$nextNumber";
    }
}

// Использование:
$nextInvoiceNumber = $sequenceGenerator->next('invoices', new InvoiceAlgorithm());
// вернет "INV-2023-0001"
