CodeIgniter for Rapid PHP Application Development

By: David Upton

Overview of this book

<p>CodeIgniter (CI) is a powerful open-source PHP framework with a very small footprint, built for PHP coders who need a simple and elegant toolkit to create full-featured web applications. CodeIgniter is an MVC framework, similar in some ways to the Rails framework for Ruby, and is designed to enable, not overwhelm.<br /><br />This book explains how to work with CodeIgniter in a clear logical way. It is not a detailed guide to the syntax of CodeIgniter, but makes an ideal complement to the existing online CodeIgniter user guide, helping you grasp the bigger picture and bringing together many ideas to get your application development started as smoothly as possible.</p>

About the Author

David Upton is a director of a specialized management consultancy company, based in London but working around the world. His clients include some of the world's largest companies. He is increasingly interested in web-enabling his work, and seeking to turn ideas into robust professional applications by the simplest and easiest route. He has so far written applications for two major companies in the UK. His other interests include simulation, on which he writes a weblog that takes up far too much of his time, and thinking.

I’d like to thank Rick Ellis for writing CI and for making it available, free. This spirit of generosity with such valuable intellectual property is what makes the Open Source movement a success, and an example to the rest of us.

I’d also like to thank Rick, and Derek Allard, for undertaking a technical review of the book and making many helpful suggestions.

Mark Barker inspired and helped me to understand Object Orientation, during many Saturday evening ‘geek-outs’.

Lastly, but not least, my thanks to Julia, John, and James for their love, support, and patience.
