如何在laravel中连接表并返回多个值？

// User.php 模型文件
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    protected $table = 'users';
    protected $primaryKey = 'id';

    public function posts()
    {
        return $this->hasMany(Post::class, 'user_id');
    }
}

// Post.php 模型文件
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $table = 'posts';
    protected $primaryKey = 'id';

    public function user()
    {
        return $this->belongsTo(User::class, 'user_id');
    }
}

// UserController.php 控制器文件
namespace App\Http\Controllers;

use App\Models\User;

class UserController extends Controller
{
    public function index()
    {
        $users = User::with('posts')->get();

        return view('users.index', compact('users'));
    }
}

// index.blade.php 视图文件
@foreach ($users as $user)
    <h2>{{ $user->name }}</h2>
    <ul>
        @foreach ($user->posts as $post)
            <li>{{ $post->title }}</li>
        @endforeach
    </ul>
@endforeach
