If you already know some PHP and are designing intelligent websites, the CodeIgniter framework is all about making your life easier. It helps you to:
Save time
Make your site more robust
Achieve more sophisticated coding
It makes coding fun again, rather than a chore
There are quite a lot of frameworks and all of them offer chunks of pre-written code that make the repetitive or complex processes of coding easier and not just for the PHP language. They impose a helpful structure on your site's development.
This book does not make any comparisons between frameworks. CI works for most, and we will see, how and why. It will be useful for you too, and you will be able to save much time and, as a result, enjoy the coding process more.
This book takes you through some of the framework's main features, and tries to explain some of what goes on "under the hood". We've used a real-world example for the code illustrations in this book to show that CI is a serious tool that can be quickly and easily used in a demanding environment.
Enjoy!
