Chapter 1—Development Concepts
Having to deal with advanced projects makes the usage of coding conventions, proper
planning, and advanced syntax unavoidable requirements.This chapter covers general
coding conventions that are a requirement for all industry-quality projects—naming
and comment conventions, as well as how to break up the source into logical modules.
Chapter 2—Advanced Syntax
This chapter covers PHP’s advanced syntax, for example multidimensional arrays,
classes, variable variables, self-modifying code, and the like.
Chapter 3—Application Design: A Real-Life Example
In this chapter, we walk you through the entire process of planning a complete Web
application: phpChat, a Web-based chat client interface to IRC.This chapter shows
planning fundamentals, gives guidelines on project organization, and shows how to
realize modular, plug-in-enabled applications.
Chapter 4—Web Application Concepts
Session management, security considerations and authentication, and usability form the
base of every Web application.Web applications aren’t possible without proper session
management.You have to find a way to recognize users during multiple page requests
if you want to associate variables like a shopping cart with one specific user. And this
identification had better be secure if you don’t want to have one user seeing another’s
credit card information. Indeed, special considerations are necessary for improving
security in your applications. Even if PHP is less prone to crackers’ attacks than other
CGI environments, it’s easy to write totally exposed applications when you don’t keep
in mind certain important principles covered in this chapter.
This chapter also introduces basic usability concepts. As soon as we begin to talk
about applications instead of stand-alone scripts, the user’s role becomes more important.
After all, it’s users who finally determine the success or failure of a project—and
this chapter shows some guidelines to achieve better user satisfaction.
