The subjects which you need to study, as a minimum, are:
- Input validation.
- Output escaping.
- Client side vs. server side information.
- Session security.
Also, remember: Never trust the client. Whatever information you get from the client can, and will, be manipulated in order to break your system.
Sounds easy, but client-side information can be found in some quite unexpected locations. Such as in
$_SERVER['REMOTE_ADDR'], and so forth.
