Laravel vs CodeIgniter
ปี 2026 เลือกอะไรดี?

// ✅ Basic Route
Route::get('/about', function() {
    return view('about');
});

// ✅ Controller Route
Route::get('/users', [UserController::class, 'index']);

// ✅ RESTful Resource (7 routes ใน 1 บรรทัด!)
Route::resource('posts', PostController::class);

// ✅ Named Route + Middleware
Route::get('/dashboard', [DashboardController::class, 'index'])
       ->middleware('auth')
       ->name('dashboard');

// ✅ Basic Route
$routes->get('about', 'PagesController::about');

// ✅ Controller Route
$routes->get('users', 'UserController::index');

// ✅ RESTful Resource
$routes->resource('posts');

// ✅ Route Group พร้อม Filter (Middleware)
$routes->group('admin', ['filter' => 'auth'], function($routes) {
    $routes->get('dashboard', 'AdminController::dashboard');
    $routes->get('users', 'AdminController::users');
});

// Model: กำหนด Relationship ครั้งเดียว ใช้ได้ตลอด
class Post extends Model {
    protected $fillable = ['title', 'body', 'user_id'];

    public function user(): BelongsTo {
        return $this->belongsTo(User::class);
    }
    public function tags(): BelongsToMany {
        return $this->belongsToMany(Tag::class);
    }
}

// Controller: ดึงข้อมูลพร้อม Relationship แบบ Eager Load
$posts = Post::with(['user', 'tags'])
    ->where('status', 'published')
    ->latest()
    ->paginate(10);

// สร้าง Record ใหม่ — ง่ายมาก
Post::create([
    'title' => $request->title,
    'body'  => $request->body,
    'user_id' => auth()->id(),
]);

class PostModel extends Model {
    protected $table      = 'posts';
    protected $allowedFields = ['title', 'body', 'user_id', 'status'];
    protected $returnType = 'array'; // หรือ 'object' ก็ได้

    // Custom method ดึง Published Posts
    public function getPublished($limit = 10): array {
        return $this
            ->select('posts.*, users.name as author_name')
            ->join('users', 'users.id = posts.user_id')
            ->where('posts.status', 'published')
            ->orderBy('posts.created_at', 'DESC')
            ->paginate($limit);
    }
}

// Controller: ใช้งาน Model
$model = new PostModel();
$posts = $model->getPublished(10);
$pager = $model->pager;
