database-driven web design, holding its own in the face of challenges from
integrated
frameworks—such as Ruby on Rails—that are harder to learn. Due to its open
source
roots (unlike the competing Microsoft .NET Framework), it is free to
implement and
is therefore an extremely popular option for web development.
Any would-be developer on a Unix/Linux or even a Windows/Apache platform
will
need to master these technologies. And, combined with the partner
technologies of
JavaScript, CSS, and HTML5, you will be able to create websites of the
caliber of industry standards like Facebook, Twitter, and Gmail.
Audience
This book is for people who wish to learn how to create effective and
dynamic websites.
This may include webmasters or graphic designers who are already creating
static web sites but
wish to take their skills to the next level, as well as high school and college
students, recent graduates, and self-taught individuals.
In fact, anyone ready to learn the fundamentals behind the Web 2.0
technology known
as Ajax will obtain a thorough grounding in all of these core technologies:
PHP, MySQL, JavaScript, CSS, and HTML5.
Assumptions This Book Makes
This book assumes that you have a basic understanding of HTML and can at
least put
together a simple, static website, but does not assume that you have any
prior knowledge of PHP, MySQL, JavaScript, CSS, or HTML5—although if you do,
your progress through the book will be even quicker.
Organization of This Book
The chapters in this book are written in a specific order, first
introducing all of the core
technologies it covers and then walking you through their installation on a
web development server so that you will be ready to work through the examples.
In the first section, you will gain a grounding in the PHP programming
language, covering the basics of syntax, arrays, functions, and object-oriented
programming.
Then, with PHP under your belt, you will move on to an introduction to the
MySQL database system, where you will learn everything from how MySQL databases
are structured to how to generate complex queries.
After that, you will learn how you can combine PHP and MySQL to start
creating your
own dynamic web pages by integrating forms and other HTML features.
Following that, you will get down to the nitty-gritty practical aspects of PHP
and MySQL development by learning a variety of useful functions and how to
manage cookies and sessions, as
well as how to maintain a high level of security.
In the next few chapters, you will gain a thorough grounding in JavaScript,
from simple functions and event handling to accessing the Document Object Model
and in-browser validation and error handling.
With an understanding of all three of these core technologies, you will
then learn how
to make behind-the-scenes Ajax calls and turn your websites into highly
dynamic environments.
Next, you’ll spend two chapters learning all about using CSS to style and
lay out your
web pages, before moving on to the final section on the new features built
into HTML5, including geolocation, audio, video, and the canvas. After this,
you’ll put together ev‐erything you’ve learned in a complete set of programs that together
constitute a fully
functional social networking website.
Along the way, you’ll also find plenty of pointers and advice on good
programming
practices and tips that could help you find and solve hard-to-detect
programming er‐ rors. There
are also plenty of links to websites containing further details on the topics
covered
