This is a listing of materials that I would recommend to other web developers.
Periodicals
Books
- Securing PHP Web Applications - Tricia and William Ballad - 2009
This is a good, easy to understand introduction to PHP security issues.
- Essential PHP Security - Chris Shiflett - 2005
Short but thorough.
- The Object-Oriented Thought Process - Matt Weisfeld - 2000
Though the book uses JAVA as the reference language, it's an excellent overview of Object Oriented Programming.
- Core PHP Programming - Leon Atkinson and Zeev Suraski- 2003
The best language reference I've found.
