[BUG] PHP 8.5: Model::toArray() throws deprecation when UPDATED_AT is null

Lisez src/Model/Concerns/HasAttributes.php, en particulier getDates() et addDateAttributesToArray(), puis recherchez les tests de sérialisation du modèle. Reproduisez le problème avec un modèle dont UPDATED_AT est null et dont CREATED_AT est défini. Le travail est terminé lorsque toArray() conserve l’heure de création et renvoie le résultat sans dépréciation lorsque l’horodatage de mise à jour est désactivé.

Description:

在 PHP 8.5.12、hyperf/database v3.2.5 环境下，模型通过
UPDATED_AT = null 禁用更新时间字段后，调用 toArray() 会触发：

Using null as an array offset is deprecated, use an empty string instead

在 Hyperf 将弃用提示转换为 ErrorException 的环境中，该问题会中断正常查询响应。

定位到 Hyperf\Database\Model\Concerns\HasAttributes：

1. getDates() 将 CREATED_AT 和 UPDATED_AT 加入日期字段列表，没有过滤 null。
2. addDateAttributesToArray() 遍历该列表并执行 isset($attributes[$key])。
3. 当 $key === null 时，触发 PHP 8.5 弃用提示。

预期行为：禁用更新时间字段的模型可以正常序列化，保留创建时间，不触发弃用提示。

建议在生成日期字段列表时过滤表示禁用时间列的 null，并增加空时间列常量的序列化回归测试。

Steps To Reproduce:

1. 使用 PHP 8.5.12 和 hyperf/database v3.2.5。
2. 在项目根目录创建 reproduce.php，内容如下。
3. 执行 php reproduce.php。该复现不需要数据库连接，也不依赖业务模型或 HTTP 请求。

<?php

require __DIR__ . '/vendor/autoload.php';

error_reporting(E_ALL);

// 模拟框架将弃用提示转换为异常的行为。
set_error_handler(static function ($level, $message, $file, $line) {
    throw new ErrorException($message, 0, $level, $file, $line);
});

$model = new class extends \Hyperf\Database\Model\Model {
    public const CREATED_AT = 'create_time';
    public const UPDATED_AT = null;

    protected ?string $dateFormat = 'Y-m-d H:i:s';
};

$model->setRawAttributes([
    'id' => 1,
    'create_time' => '2026-11-12 12:00:00',
]);

var_export($model->getDates());
var_export($model->toArray());

实际结果：

array (
  0 => 'create_time',
  1 => NULL,
)

ErrorException: Using null as an array offset is deprecated,
use an empty string instead

vendor/hyperf/database/src/Model/Concerns/HasAttributes.php:731
vendor/hyperf/database/src/Model/Concerns/HasAttributes.php:122
vendor/hyperf/database/src/Model/Model.php:879

预期 toArray() 返回：

[
    'id' => 1,
    'create_time' => '2026-11-12 12:00:00',
]
