下面是我的Laravel应用程序的代码：

public function sendNotifications()
    {
        $matchingSubscriptions = DB::table('tournament_match_plan')
            ->join('push_subscriptions', 'push_subscriptions.age_group', '=', 'tournament_match_plan.league')
            ->where('tournament_match_plan.start', '=', '11:20:00')
            ->where('tournament_match_plan.team_1', '=', 'push_subscriptions.club')
            ->orwhere('tournament_match_plan.team_2', '=', 'push_subscriptions.club')
            ->get();

        dd($matchingSubscriptions);
}

下面是调试消息：

Illuminate\Support\Collection {#751 ▼ // app\Http\Controllers\Guests\GuestsPushController.php:97
  #items: []
  #escapeWhenCastingToString: false
}

为什么我的Laravel代码没有任何结果？
我在phpMyAdmin中尝试了相同的查询：

SELECT *
FROM tournament_match_plan
JOIN push_subscriptions ON push_subscriptions.age_group = tournament_match_plan.league
WHERE tournament_match_plan.start = '11:20:00'
AND (tournament_match_plan.team_1 = push_subscriptions.club OR tournament_match_plan.team_2 = push_subscriptions.club);

通过上面的代码，我得到了正确的结果。
