Book Review: CodeIgniter 1.7 Professional Development
I was recently asked to review Packt Publishing’s new book, CodeIgniter 1.7: Professional Development, by fellow CodeIgniter community member, Adam Griffiths. Adam is a well-known developer in the CI community, who, despite his young age, has become well-known among the ranks of CodeIgniter developers with his open source contributions.
I’m always excited to see new CodeIgniter books published, as the framework is growing in popularity and credibility among PHP developers, with applications springing up across the Internet. The framework is known for its excellent user guide and a strong community backing. But sometimes the resources available aren’t quite enough to make the concepts click in a new developer’s mind.
For me, the process involved viewing some of the available screencasts and looking at code that other had written in their applications. It wasn’t hard, but Adam’s new book would have been helpful to me in those early days of development with CodeIgniter. A selection of other CI-focused books have been published in the past, but I haven’t found many to be as practical as Adam’s. In previous books, often a single sample project is selected and used throughout the book to explain all of the concepts.
Adam’s approach is quite different and takes a look at various pieces of functionality that application developers might find very useful, while not walking them through the entire process of building an example application.
Specifically, Adam’s examples of using Twitter and Facebook authentication as well as accessing RESTful web services prove very useful, as these functions are increasingly at the core of many applications being built today.
The book also spends a bit of time talking about the basics of style in PHP coding. A guide like this would have helped to alleviate the evolution of coding style I’ve experienced as I’ve spent more and more time building web applications. It provides a solid baseline, referencing the CodeIgniter documentation’s style guide as a resource for maintaining code consistency.
Overall, I think that CodeIgniter 1.7: Professional Development fills a void in the market for CodeIgniter resources. I’d certainly recommend it to someone just starting out with the framework as an additional resource to use alongside the various other community resources.
The new book is not without its flaws though. As good as it is at helping a new developer get started at building all parts of an application: models, views, controllers and libraries, the one piece that’s lacking is advice on how to integrate with other people’s code. There a wealth of pre-written code out there, which though it may not be built to work with CodeIgniter, can save developers a ton of time as they build applications—if they know how to properly connect with third-party libraries from within the CodeIgniter framework. It can be a little bit tricky at first, so a primer in that area would be ideal.
Additionally, opening up the book with a bit of prior PHP experience is advised. Sometimes the examples don’t fully explain what’s going on in the code, so it could be a little complicated for a complete beginner.
Overall, though, I’m impressed with the direction this book goes. The angle is good, with a focus outside of the typical ‘build a blog in 20 minutes’ example.
