💡 DTO trong PHP: giúp truyền dữ liệu giữa các lớp một cách an toàn, rõ ràng. Dùng lớp readonly (PHP 8.1) để tạo đối tượng bất biến, hỗ trợ IDE nhận dạng thuộc tính. Thêm factory static từ Request hay array để tạo DTO nhanh. Giảm lỗi khi dùng mảng associative và cải thiện maintainability. #PHP #DTO #LậpTrình #ThiếtKế #Backend #SoftwareDesign #DesignPattern

Áp dụng Repository Pattern trong Laravel giúp tách lớp truy cập dữ liệu, giảm query trùng lặp, dễ test và mở rộng. Tạo Interface, triển khai Repo, bind trong ServiceProvider, rút gọn Controller. Thêm BaseRepository cho CRUD chung, mở rộng cho Product. Bắt đầu với model phức tạp nhất. #Laravel #RepositoryPattern #PHP #CleanCode #LaravelVietnam #Coding #PhátTriểnWeb #WebDev
