CodeIgniter is an open-source PHP framework build for RAD.
The book CodeIgniter 1.7 from PacktPublishing, written by  Jose Argudo Blanco and David Upton is trying to build an overall image of of the CodeIgniter framework,  as an addintion to the user guide.

The book is not a reference, and that becomes obvious with every chapter, each time a new feature of the CodeIgniter framework is introduced the user is directed to the corresponding page of the module in the user guide or wiki. Even more, suggestions are made for alternative modules that can achieve a similar task in a different way.

Authors say that only minimal knowledge of PHP is necessary to read this book, a promise that is hard to keep in my opinion, usually books that target novice to medium skill readers are saying something like that. To my surprise they ware right, the reader only needs PHP4 knowledge. And when it comes to OOP not even PHP5 features are required, just the PHP4 object model. In this book even the copping objects by reference is described! Of course copping objects by reference is no longer a relevant issue with PHP5, but taking this in to consideration that is an PHP4 framework it was a good idea to mention and explain it. It seems like there are still PHP4 server on the Internet… that is just sad…

Reading the book flashbacks came to my mind with pieces of code written directly in PHP and the hell of debugging them, trying to understand other peoples code… what times… horribly of course. The reasoning behind this concepts of re usability in a framework is just  great: “Possibly you like typing regex. Some people like lying on a bed of nails…”. When a developer, especially a beginner, is reading something like this it makes him understand that you don’t have to reinvent the wheel each time, but just use solutions already developed by others.

Comparing between different available solutions I believe is the most funny part of a book like this. Is difficult or even impossible to compare for instance Zend Framework or even CakePHP with CodeIgniter. After all almost all frameworks say the same thing, just download and start working. Personally when I need to use a module from Zend Framework I just load the autoloader and get to work. The comparison shows CodeIgniter as a winner for most users, as expected, the reasoning behind that claim is pretty honest.  Afterall is a small framework and does not have complex features like autogenerating CRUD. I remember a Java book where the author was representing the fact that C++ is faster then Java as a disadvantage, of course was just silly.

I sometimes had the impression that the terms were wrongly defined. The authors are using “small” mistakes in terms to explain what’s actually happening in the background. When you are working with MVC frameworks some of the notions are simple and obvious, but for a developer that’s not familiar with that terms there are quite hard to comprehend.

And to continue with the mistakes in the book, I’ve found a few. Quite a difficult moment when you start learning something new. Fortunately there are quite obvious because they result in errors, and if you read chapter after chapter you’ll know what the issue is and how to fix it.

Examples are pretty consistent and well documented. When a new concept or module is introduced it is fully explained in detail.

The resulting apps are not very complex, for instance at the end of the book there isn’t a full complex app like a CMS, rather modules and the way there are combined is explained. The user will have to decide in the end how will his app look and feel. For instance in chapter 13 pagination and ordering is explained. When pagination is used everything is OK, but when ordering is introduced the pagination begin to slip. It took me about 5-10 minutes to fix the issue, but it would have been nice for the authors to fix the issue themselves.

Overall is a good book, especially for users that have no prior knowledge of CodeIgniter, is just like is presented by the authors, a book for developers that want more productivity in there work or just what to see what other tools are out there.  The book does not present full solutions like a CMS or a shopping cart, but rather what this framework has to offer.

An advanced developer can understand from this book the structure of the CodeIgniter framework, possibly to compare it to other popular frameworks, without loosing time with complex and irrelevant examples.

More then an year ago I wrote a blog, where I was telling that Google doesn’t know where I live.

The issue was that Goole Maps had a very poor coverage for Romania, and Yahoo! Maps is a way better alternative for this part of Europe. I still believe that Yahoo! Maps is a better alternative but I was surprised by one thing. Occasionally I’ve visited Google Maps to see how things are going with the coverage of Bucharest, basically it was represented a single way to cross the city from highway A1 to A2, and nothing else.

About a month ago, I went back to check what was new because I needed to build an Romanian tourism app and… surprise, surprise, even though the satellite photos are of lower quality now, I could find my street using the search and even the block where I live. Even more I was able to calculate alternative routes to various  locations in Bucharest.

It looks like Google has began to have a little more interest in this part of central Europe, now allowing for a real competition with Yahoo!. This is a great advantage for Android phone users who use Google Maps for there GPS app. Few years ago, to user Google Maps in Romania it was completely useless, you could see the satellite images, but that was about all, you could not find useful addresses, and if there ware marked on the map you could not automatically find a route to them.

Eventually I used Google Maps for my app, even though I still believe that Yahoo! Maps is a good alternative, as far as quality and API. Speaking of API, both of them seem ok and I don’t king that’s a criteria to difference them between the two giants.

A thing a little shocking about Google knowing where I live it was on an evening when curios to see if my GPS works on my mobile phone I went on my balcony. Everything was ok, it found me within 50 and 100m on the Google map, using my wireless connection for the data transfer. Another evening a friend came over to tried the same thing, using the same connection to the Internet, same Google Maps app, and he was found within 100m.

Nothing unusual in theory, but everything changed  the next day when he told me that his phone didn’t have GPS, and what we ware seeing was the date from the last time I connected my device… so Google now knows where I live… literary…

It seems like Oracle received the unconditional approval from EU to by Sun according to Yahoo! News.

About and year and a half ago I was considering the MySQL Certified Developer exam. Now I’ve become Sun MySQL Certified Developer and it seems like I’ll even become Oracle MySQL Certified Developer. And all of this with no extra charge! 🙂

The good part is that we’ll become Oracle developers even if we don’t want or plan to (ok, is not exactly Oracle, but one of there products).

Another year has passed and PHP 6 is still not here…

But that’s not exactly news, is the 4-th year when this long awaited version is not released. Not for nothing is called the most awaited version.

But overall it was a good year for the community, even though we still don’t have native Unicode in a stable version now we have all other awaited features in PHP 5.3, which will probably need another few years to become used on a large scale.

Even though everyone was expecting last year for Oracle to enter in full force on medium and small database market by purchasing Sun, enlarging it’s already well established  portfolio on the enterprise market. It seems that it was not to be, CE is still analyzing the deal.

However MySQL is not what it used to be 5-6 years ago, when nobody dared to use it for enterprise products. This days MySQL is a product ready to be used in both small and large products that require a lot of scalability.

But back to the year that just ended, it was a full year, even with this economic crises.

CodeIgniter is an open-source PHP framework, build for RAD development. This framework is continuously growing in popularity, probably especially since people realized that is much easier to use an open-source framework instead of developing an internal one, but that’s another story. The CodeIgniter 1.7 book from PacktPublishing, written by Jose Argudo Blanco and David Upton is building a big picture about the CodeIgniter 1.7 framework, as an addition to the reference manual.

After all every respectable framework has an detailed reference, with usability examples, more or less comprehensible. When it comes to learning an framework (and not only), an reference is usually not the best place to start from, because is hard to get the big picture when you can only receive atomic answers. That’s why we buy books this days, to have a general image with problems and solutions. And this is where the CodeIgniter 1.7 book comes in.

Initially, when I’ve seen that the title has the version number of the analyzed framework I was a little pessimistic, because usually when you buy a book you don’t want it to be tight up to particular version, isn’t it? Well, not exactly… I had a similar issue with Zend Framework, most books use “older versions”  (ex: 1.5-1.6) and I wanted to see an approach using the new features from version 1.8 or greater. After all when you start learning something you usually want the latest version of the framework or what ever it is that you are learning, and when new features appear it will be much easier to simply look then in the reference guide since you already know the basics.

This book seams to start from the beginners level and progressively describe both basic elements as well as the most common problems the user may encounter when developing apps using the CodeIgniter framework.  The sample chapter, looks pretty well structured and easy to understand, and from the table of contents it seams to approach all the important subjects. With the hope that the rest of the book will be just as well structured (I’m actually judging a book by the cover?) and a second part to this review will follow I can’t barely wait for the book.

To be continued…
