Chapter 5: Relational Database Design

Although you'll have worked with a very simple sample database in the previous

chapters , most database driven web sites require the storage of more complex

forms of data than you'll have dealt with to this point. Far too many database

driven web site designs are abandoned midstream or are forced to start again

from the beginning, because of mistakes made early on during the design of the

database structure. In this critical chapter you'll learn the essential principles

of good database design, emphasizing the importance of data normalization. If

you're unsure what that means, then this is definitely an important chapter for

you to read!

Chapter 6: Structured PHP Programming

Techniques to better structure your code are useful in all but the simplest of

PHP projects. The PHP language offers many facilities to help you do this, and

in this chapter, I'll cover some of the simple techniques that exist to keep your

code manageable and maintainable. You'll learn to use include files to avoid

having to write the same code more than once when it's needed by many pages

of your site, and I'll show you how to write your own functions to extend the

built-in capabilities of PHP and to streamline the code that appears within your

scripts.

Chapter 7: A Content Management System

In many ways the climax of the book, this chapter is the big payoff for all you

frustrated site builders who are tired of updating hundreds of pages whenever

you need to make a change to a site's design. I'll walk you through the code for

a basic content management system that allows you to manage a database of

jokes, their categories, and their authors. A system like this can be used to

manage simple content on your web site; just a few modifications, and you'll

have a site administration system that will have your content providers submit-

ting content for publication on your site in no time—all without having to know

a shred of HTML!

Chapter 8: Content Formatting with Regular Expressions

Just because you're implementing a nice, easy tool to allow site administrators

to add content to your site without their knowing HTML, that content can still

contents of your database—tweaks that allow it to incorporate simple formatting

such as bold or italicized text, among other options.

Chapter 9: Cookies, Sessions, and Access Control

What are sessions, and how are they related to cookies, a long-suffering techno-

logy for preserving stored data on the Web? What makes persistent data so im-

portant in current ecommerce systems and other web applications? This chapter

answers all those questions by explaining how PHP supports both cookies and

sessions, and explores the link between the two. You'll then put these pieces

together to build a simple shopping cart system, as well as an access control

system for your web site.

Chapter 10: MySQL Administration

While MySQL is a good, simple database solution for those without the need

for many frills, it does have some complexities of its own that you'll need to

understand if you're going to rely on a MySQL database to store your content.

In this section, I'll teach you how to perform backups of, and manage access to,

your MySQL database. In addition to a couple of inside tricks (like what to do

if you forget your MySQL password), I'll explain how to repair a MySQL database

that has become damaged in a server crash.

Chapter 11: Advanced SQL Queries

In Chapter 5 we saw what was involved in modeling complex relationships

between pieces of information in a relational database like MySQL. Although

the theory was quite sound, putting these concepts into practice requires that

you learn a few more tricks of Structured Query Language. In this chapter, I'll

cover some of the more advanced features of this language to help you juggle

complex data like a pro.

Chapter 12: Binary Data

Some of the most interesting applications of database driven web design include

some juggling of binary files. Online file storage services are prime examples,

but even a system as simple as a personal photo gallery can benefit from storing

binary files (that is, pictures) in a database for retrieval and management on the

fly. In this chapter, I'll demonstrate how to speed up your web site by creating
