如何在laravel中从查询结果中获取数据

$users = DB::table('users')->where('active', true)->get();

$users = User::where('active', true)->get();

foreach ($users as $user) {
    echo $user->name;
}

$user = User::where('active', true)->first();
echo $user->name;

$names = User::pluck('name');
foreach ($names as $name) {
    echo $name;
}

$count = User::where('active', true)->count();
echo $count;
