Sử dụng cookie trong PHP - quản lý đăng ký & đăng nhập tài khoản trong PHP - Lập Trình PHP

Viết chương trình thực hiện các chức năng sau

- Thiết kế trang đăng ký tài khoản gồm các trường : họ tên, email, password, địa chỉ

-> khi người dùng click đăng ký => thêm thông tin vừa đăng ký vào cookie

- Thiết kế trang đăng nhập => gồm 2 trương email và mật khẩu => khi người dùng vào thông tin đúng vs thông tin trang đăng ký => chuyển sang trang welcome
