I am developing a event organization website. Here when the user registers for an event he will be given a unique random number(10 digit), which we use to generate a barcode

Answer 1

 $id]);
                foreach ($whereParams as $param) {
                    $query->where(...$param);
                }
                if (!$query->first()) {
                    return $id;
                }
            }
        } catch (\Throwable $e) {
            $exceptionMessage = $e->getMessage();
        }

        throw new GeneratorException($exceptionMessage);
    }

    protected static function IDGenerator(): ?\Generator
    {
        for ($i = 1; $i <= self::$limitIterations; $i++) {
            yield (string)random_int(1000000000, 9999999999);            
        }
        return null;
    }
}

sample usage

$card->number = GeneratorHelper::generateID(Card::class, 'number');
