CodeIgniter 1.7

Overview of this book

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. 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. This book will start you from the basics, installing CodeIgniter, understanding its structure and the MVC pattern. You will also learn how to use some of the most important CodeIgniter libraries and helpers, upload it to a shared server, and take care of the most common problems. If you are new to CodeIgniter, this book will guide you from bottom to top. If you are an experienced developer or already know about CodeIgniter, here you will find ideas and code examples to compare to your own.

New versions of CI come up from time to time. They come with comprehensive instructions for updating. Usually, this involves copying a new set of files to your CI_system folder. Sometimes, you need to change config files, or your index.php file as well. Because the folder structure keeps your application files in their place, it's usually easy to update the system without touching the applications.

But, say you've written your killer application in version 1.7.1. It's uploaded to your production system and is working fine. Then CI version 1.7.2 comes out (or 2.8 or whatever…). It has interesting new features and some bug fixes. Do you upgrade to it?

We would say, "Yes", if it's a minor upgrade. But if it's a major version change, and your existing system is working fine, it may take some more time to update it, so you will need to decide if the changes are going to help you or not. You can tell the difference partly from the numbering...
