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.

We've set up databases, used FTP, built tests, and started to email the test results. But it's easy to get caught in techie things and forget that websites are often judged on presentation, on how well they process data, and how appropriately they display it to human users.

Here are a few CI classes that help with some problems that arise regularly when you are building a website, particularly when it comes to delivering dynamic information to your users:

  • The date helper translates different date formats and helps you to cope with time zones. With the help of the calendar class, we will quickly generate a calendar.

  • The text helper provides useful functions to manipulate and convert strings.

  • The language class makes it easier to write websites that display the same information in different languages, depending on user preference...
