Overview of this book

<p>CodeIgniter is an open source PHP framework with a small footprint and exceptional performance. It gives you a rich set of libraries for common tasks, with a simple interface to access them. There are several unexplored aspects of CodeIgniter that can help developers build applications more easily and quickly. In this book, you will learn the intricacies of the framework and explore some of its hidden gems.<br /><br />If you want to get the most out of CodeIgniter, this book is for you. It teaches you what you need to know to use CodeIgniter on a daily basis. You will create mini-applications that teach a specific technique and let you build on top of the base. <br /><br />This book will take you through developing applications with CodeIgniter. You will learn how to make your CodeIgniter application more secure than a default installation, how to build large-scale applications and web services, how to release code to the community, and much more. You will be able to authenticate users, validate forms, and also build libraries to complete different tasks and functions.<br /><br />The book starts off introducing the framework and how to install it on your web server or a local machine. You are introduced to the Model-View-Controller design pattern and how it will affect your development. Some important parts of the CodeIgniter Style Guide are included to keep CodeIgniter development as standardized as possible; this helps greatly when working as part of a team or taking on an old CodeIgniter project. You will quickly move on to how CodeIgniter URLs work and learn about CodeIgniter-specific files such as helpers and plugins. By the time you finish this book, you will be able to create a CodeIgniter application of any size with confidence, ease, and speed.</p>

Defining our goals


Before we go ahead and jump into writing code, we need to define what we need to do. Setting goals before we write code is beneficial in three ways.

Firstly we will know all of the features that our code should have, and can limit ourselves to just that, which will eliminates scope creep (also known as feature creep).

Secondly, when given a set of goals, we can visualize how we will write the code in our heads. If you know what to expect at the end, you can build it much faster, because you will already know what it should look like.

Finally, once we finish writing our code we can go back and check if we have met all of our goals. This helps us to decide whether or not we were successful. If for some reason we did not meet a goal, we could consider it a failed project unless there is a good reason for this. For example, we could start writing a portion of code and realize that there is a better way of doing it. In this case, not meeting the goal would be a good thing. But...
