- Object & Array trong PHP
- Mã hoá trong PHP
- md5: string -> md5 encode -> string encrypt -> khong de dich nguoc ve original string:
- md5($password)
- md5(md5($password) + PRIVATE_KEY)
- base64: string -> base64 encode -> string code -> base64 decode -> orignal string.
- Form
- Dky thanh cong -> welcome.php -> Hello FullName
(fullname <> null & $password == $confirm_pwd)#welcome.php
