Chapter 1 explains what CodeIgniter can do, the 'framework', and how CodeIgniter fits in. It further talks about the open-source business model and gives some disadvantages of CodeIgniter, at the end.
Chapter 2 explains what happens when you install the site, and which files will be created. It gives a detailed overview of the required software, and explains the basic configuration of CodeIgniter.
Chapter 3 explains how MVC helps to organize a dynamic website. It goes further to explain the process by which CodeIgniter analyzes an incoming Internet request and decodes which part of your code will handle it. Then CodeIgniter syntax rules and the different types of files or classes you can find—or write for yourself—on a CodeIgniter site are explained. At the end of the chapter, some practical hints on site design are given.
Chapter 4 looks at how you set up a database to work with CodeIgniter, and then how you use the Active Record class to manipulate the database.

In this book, we have assembled the most important topics that programmers and search engine marketers
should know about when designing web sites.

At the end of Chapter 1, You: Programmer and Search Engine Marketer, you create the environment where you’ll be coding away throughout the rest of the book. Programming with PHP can be tricky at times; in order to avoid most configuration and coding errors you may encounter, we will instruct you
how to prepare the working folder and your MySQL database. If you aren’t ready for these tasks yet, don’t worry! You can come back at any time, later. All
programming-related tasks in this book are explained step by step to minimize the chances that anyone gets lost on the way.
Chapter 2, A Primer in Basic SEO, is a primer in search engine optimization tailored for the IT professional. It stresses the points that are particularly relevant to the programmer from the perspective of the programmer. You’ll also learn about a few tools and resources that all search engine marketers and web
developers should know about.

This book teaches how to develop dynamic Web sites with PHP and MySQL, covering
the knowledge that most developers might require. In keeping with the format of the
Visual QuickPro series, the information is discussed using a step-by-step approach
with corresponding images. The focus has been kept on real-world, practical examples,
avoiding “here’s something you could do but never would” scenarios. As a practicing Web
developer myself, I wrote about the information that I use and avoided those topics
immaterial to the task at hand. Asa practicing writer, I made certain to include topics
and techniques that I know readers are asking about.
The structure of the book is linear, and the intention is that you’ll read it in order.

It begins with three chapters covering the fun damentals of PHP (by the second chapter,
you will have already developed your first dynamic Web page). After that, there are
three chapters on SQL (Structured Query Language, which is used to interact with all
databases) and MySQL. They teach the basics of SQL, database design, and the MySQL
application in particular. Then there’s one chapter on debugging and error manage-
ment, information everyone needs. This is followed by a chapter introducing how to
use PHP and MySQL together, a remarkably easy thing to do.
The following five chapters teach more application techniquesto round out your
knowledge. Security, in particular, is repeatedly addressed in those pages. Chapter 14,
“Making Universal Sites,” is entirely new to this edition of the book, showing you how

to broaden the reach of your sites. Finally, I’ve included three example chapters, in

which the heart of different Web applications are developed, with instructions.

Is this book for you?
This book was written for a wide range of people within the beginner-to-intermediate
range. The book makes use of XHTML for future compatibility, so solid experience
with XHTML, or its forebear HTML, is a must. Although this book covers many
things, it does not formally teach HTML or Web page design. SomeCSS is sprinkled
about these pages but also not taught. Second, this book expects that you have one
of the following:
- The drive and ability to learn without much hand holding, or…
- Familiarity with another programming language (even solid JavaScript skills About This

Book would qualify), or…
- Acursory knowledge of PHP Make no mistake: Thisbook covers PHP and MySQL from Ato Z,

teaching everything you’ll need to know to develop real-world Web sites, but

particularly the early chapters cover PHP at a quick pace. For this reason I
recommend either someprogramming experience or a curious and independent spirit
when it comes to learning new things. If you find that the material goes too quickly,

you should probably start off withthe latest edition of my book PHP for the World Wide
Web: Visual QuickStart Guide, which goes at a more tempered pace.
No database experienceis required, since SQL and MySQL are discussed starting at a
more basic level.

This handy little book offers programmers a complete overview of the syntax and semantics of regular expressions that are at the heart of every text-processing application.

Developing a new web application should not mean reinventing the wheel. That's why a framework is an essential item in your development toolbox. It helps you respect coding standards; write bulletproof, maintainable code; and focus on business rules rather than waste time on repetitive tasks. This book introduces you to symfony, the leading framework for PHP developers, showing you how to wield its many features to develop web applications faster and more efficiently, even if you only know a bit of PHP.

In The Definitive Guide to symfony, you will learn about the Model-View-Controller architecture and the crucial role it plays in making frameworks like symfony possible. The book also covers framework installation and configuration, and shows you how to build pages, deal with templates, manage requests and sessions, and communicate with databases and servers. You will see how symfony can make your life easier by effectively managing form data, enhancing the user experience with Ajax, internationalizing applications for a global audience, and using smart URLs. Authors François Zaninotto and Fabien Potencier put a strong emphasis on the tools that symfony provides for professional environments, showing you how to take advantage of unit tests, scaffolding, plug-ins, the command line, and extensible configuration. And since frameworks often raise performance-related debate, this book will give you many tips and techniques for monitoring and improving your application's performance, from caching to expert configuration tweaks.

For those of you who develop standalone Windows applications for PCs and other devices, Microsoft's .NET Windows Forms provide a much better way to get it done. This new technology gives you more power and flexibility for a fraction of the effort compared to classic Win32 development, with a streamlined programming model that deals automatically with many tedious details that once plagued developers. As with most things .NET, the only hitch is the learning curve. But that's where acclaimed author Jesse Liberty makes the difference with Programming .NET Windows Applications. With this tutorial, you will explore all aspects of using .NET Windows Forms class libraries and the associated programming tools in Visual Studio .NET, enabling you to build applications for the Windows 9x, Windows 2000 and Windows XP desktop platforms. Step-by-step, you'll learn ways to design applications that either function alone on a PC, or work in combination with your web-based application server to take advantage of the richer interface and higher level of security. The book also explains how your new Windows applications can sidestep problems that used to arise from the use of DLLs (known collectively as "DLL hell"), and how .NET Windows Forms can be used as an alternative to ASP.NET and browser-based approaches for building web application clients. Jesse Liberty definitely knows his stuff when it comes to the .NET platform. As the author of O'Reilly's Programming C# and Learning Visual Basic .NET, he's well-known for his clear and concise style that prompted one reviewer to say, "It's as if he knows exactly what questions I'm going to ask ahead of time." Jesse also co-authored Programming ASP.NET with contract programmer Dan Hurwitz, and now the two have teamed up again to bring you this comprehensive tutorial--without a doubt, the best source available for learning how to program with .NET Windows Forms.
