Pro PHP XML and Web Services ReviewThis is first and foremost an XML reference. The author takes the reader through over 100 pages XML background in the first three chapters, then an overview of a few utilities like XPath and XPointer before he touches on PHP. Having provided some grounding in the basics, he then proceeds to develop the use of XML in PHP from the basic topics of DOM (Document Object Model) and XSLT (Extensible Stylesheet Language Transformations) to the more advanced topics of SOAP (Simple Object Access Protocol) and web services.
Along the way Richards introduces the reader to utility classes like SimpleXML, SAX (Simple API for XML), XMLReader. He also touches on PEAR (PHP Extension and Application Repository) utility classes and topics like security, RSS (Really Simple Syndication) and UDDI (Universal Description, Discovery and Integration). The author's examples are reasonably concise and readable; making the necessary points without getting carried away.
The bottom line is that this is a highly effective reference (that means fairly comprehensive, but dry reading; I read cover to cover, but it was relatively tedious) on XML and its varied uses in association with PHP. This is not a book for the newcomer to programming, nor is it a cookbook for examples for the casual programmer/web developer, although the author does provide PEAR examples for connecting with major web services like Amazon, Google and Yahoo (among others). My suggestion for readers is to review what you need of the first 11-12 chapters to ensure a firm grounding in XML, and then hop to the chapters specific to the problem being faced.
P-)Pro PHP XML and Web Services Overview
Pro PHP XML and Web Services is the authoritative guide to using the XML features of PHP 5 and PHP 6. No other book covers XML and Web Services in PHP as deeply as this title. The first four chapters introduce the core concepts of XML required for proficiency, and will bring you up to speed on the terminology and key concepts you need to proceed with the rest of the book. Next, the book explores utilizing XML and Web Services with PHP5. Topics include DOM, SimpleXML, SAX, xmlReader, XSLT, RDF, RSS, WDDX, XML-RPC, REST, SOAP, and UDDI.

Author Robert Richards, a major contributor to the PHP XML codebase, is a leading expert in the PHP community. In this book, Richards covers all topics in depth, blending theory with practical examples. You'll find case studies for the most popular web services like Amazon, Google, eBay, and Yahoo. The book also covers XML capabilities, demonstrated through informative examples, in the PEAR libraries.

Ajax in Action ReviewLet me first preface this review by saying this is the first technical book that I've read cover to cover TWICE prior to posting a review. I had to make sure the stuff stuck, because the material covered in Manning's very excellent "Ajax in Action" is really deep. But bringing the next evolution of user experience, giving your web applications a rich client feel, isn't completely easy. This won't scare you away from using Ajax in your existing applications, but make you aware of exactly what to expect.
The book first starts out by presenting a healthy discussion of the key components of remote scripting - CSS, the DOM, JavaScript's XmlHttpRequest object and client callbacks - and how they interact within the scope of your project. Before diving into full-on Ajax development, authors Dave Crane and Eric Pascarello discuss the need for object-oriented JavaScript programing, which will be foreign and awkward to most developers, even those coming from procedural backgrounds like Java and C++. The authors familiarize you with the various ways of composing the unconventional constructs available (JSON-RPC, prototypes) for optimizing remote scripting.
Best practices are encouraged throughout the chapters and enforced in all code snippets. The use of patterns like Observer, Command and MVC and refactoring and module-based programming (mainly .NET assemblies and Java servlets) permeate the entire work. The actual meat of the book doesn't get started until Chapter 9, which the authors clearly state, dealing with the aforementioned discussion of raw JavaScript programming that'll be completely new to most people. But for those not wanting to engage in the massive task of writing syntax by hand, the major libraries available are thankfully referenced.
The book also isn't a "copyist's" title, one that can provide working code right out of the gate. Also, the audience for this work should be fairly sopisticated and experienced with modern-day web programming, as the book assumes a certain level of competency and doesn't waste time with rudimentary concepts or examples. Crane and Pascarello take a platform-agnostic look at incorporating Ajax-style programming into web applications, citing examples in PHP, Java and .NET, and accordingly the examples are all partial and abstracted, to be implemented in whatever platform the developer/reader is familiar with.
This is also one of the few books that I've ever recommended people read the appendices in addition to the chapters. Most titles have supplementary info that doesn't match the flow of the chapters, or exclusionary stuff you can skip, but this book is really a tome of good reading. Appendix B is an outstanding discussion on JavaScript OOP, providing an introduction to and examples in JSON.
Ajax programming is a lot more complex than it lets on, but not as daunting as you might think. This book is critical in your understanding of how to make the next big thing in web development to work for you. A must-have.Ajax in Action Overview
Val's Blog "A tremendously useful field guide specifically written for developers down in the trenches...waiting for the killer solution..."

Web users are getting tired of the traditional web experience. They get frustrated losing their scroll position; they get annoyed waiting for refresh; they struggle to reorient themselves on every new page. And the list goes on. With asynchronous JavaScript and XML, known as "Ajax," you can give them a better experience. Once users have experienced an Ajax interface, they hate to go back. Ajax is new way of thinking that can result in a flowing and intuitive interaction with the user.

Ajax in Action helps you implement that thinking--it explains how to distribute the application between the client and the server (hint: use a "nested MVC" design) while retaining the integrity of the system. You will learn how to ensure your app is flexible and maintainable, and how good, structured design can help avoid problems like browser incompatibilities. Along the way it helps you unlearn many old coding habits. Above all, it opens your mind to the many advantages gained by placing much of the processing in the browser. If you are a web developer who has prior experience with web technologies, this book is for you.

Ruby Cookbook (Cookbooks (O'Reilly)) ReviewI have a confession to make. Over more than twenty years as a programmer I'd never really had my head around object-oriented programming. I started out using C and then tried PHP and Perl and treated both as purely procedural languages (indeed, one Perl guru looked at my code and said "you were a C programmer weren't you"; humbling). Java, JavaScript, C++ and even Objective C had their turn at getting me to convert but none took (though I do code JavaScript under sufferance) until Ruby. A few month ago I started using Rails and became hooked on it and the underlying language. My Rails and Ruby skills have progressed in leaps and bounds. I've already had a good read of "Programming Ruby" and "Agile Web Development with Rails" and enjoyed and learnt from both.
I also have to admit to loving the O'Reilly "Cookbook" series. Several, particularly the "Perl Cookbook", have pride of place on the bookshelf closest to my computer. So the "Ruby Cookbook" by Lucas Carlson and Leonard Richardson was eagerly awaited. The "Cookbook" series are designed to provide you with a plethora of code examples to guide you in writing your own code. I'm definitely a hands-on style of learner and the Cookbook series suits my style - I can start getting my hands dirty with complex problems knowing I have help to code my way of out of the tight spots. This one covers a wide range of tasks from simple, such as walking a directory tree or manipulating text and numbers, through to more complex such as working with AJAX in Ruby on Rails. If you have't previously come across a book in this style then each chapter is broken up into a number of 'recipes' with a problem, a solution and then discussion of the solution.
This sort of book lives and dies by two criteria - the quality of the code and the usefulness of the recipe selection. "Ruby Cookbook" wins on both. The topics covered are wide and leave little, if any, part of the language unexplained. They start with data and structures such as strings and hashes before moving on to code blocks, objects, classes and modules. There is then an intriguing chapter on reflection and metaprogramming that I am still puzzling through before the book moves on to more internet based topics such as XML, HTML, web and internet services and, of course, Rails. The book then proceeds with chapters on the necessary housekeeping of development such as testing, packaging and automating tasks with Rake before finishing with extending Ruby with other languages and system administration tasks. The code is well written; clear and well commented, easily understandable by a virtual newb like me. The discussion is fairly clear, seemingly concise while allowing you to understand the code and how it might be changed for particular purposes.
I'm not going to go into more details as to the contents but instead point you to the book's page at O'Reilly which includes a link to the contents, listnig all the recipes in the book, and two example chapters; Chapter 7 on code blocks and iteration and Chapter 15 devoted to Rails. Together they will give you a good feel for the style and contents of the book.
The book is well written and well edited. I've already tried over a dozen of the recipes and haven't found a single code error, so my faith in the other 300 or so has risen considerably. The discussion that accompanies each recipe is a marvelous way of learning just that little bit more about the language. I found them quite good, though the odd one could do with further explanation if the book is to stand on its own - for example the discussion accompanying the recipe to iterate over a hash was not perfectly clear on the difference between Hash#each and Hash#each_pair.
At more than 800 pages this is a large and extensive volume, though the price may make you wince. Usually programming books this large have at least part of their size dedicated to something I refer to as pseudo-padding, some sort of reference or simple language explanation - this one has neither, all of it is devoted to the recipes.
With Ruby use, thanks in no part to the popularity of Rails, growing by leaps and bounds I'm sure this volume will be a well deserved bestseller. I give it four stars and recommend it to all but the most expert Ruby programmers. For beginners who, like me, appreciate hands on learning it is a must.Ruby Cookbook (Cookbooks (O'Reilly)) Overview

PHP Cookbook: Solutions and Examples for PHP Programmers ReviewThis is my first O'Reilly book in the "Cookbook" series. At first I thought this book would probably contain the code and instructions for building a couple of web applications such as a shopping cart or a blog engine. This isn't that book. Rather it provides the reader with code snippets that can be used as building blocks for all kinds of applications. If I had to describe this book in one sentence I would say it is as if the author took down all the "Hmm..., I wonder how that is done?" questions and created an answer key.
One thing I like about this book is that the authors don't waste the first few chapters trying to teach or give an overview of the language. Instead they hop right into the usage of the language that relates to real world stuff.
So here is a brief overview. The book covers PHP 5 and goes over many of the new and improved features. The first six chapters provide recipes for more basic subjects (strings, numbers, dates & times, arrays, variables, and functions. Again, this isn't an intro to PHP, that is another book such as Programming PHP from O'Reilly. This is that book you reach for once you have moved from PHP basics and are ready to build some real world stuff.
By chapter seven the authors are discussing classes and objects. I like using classes when coding in C++, so this is a good chapter for those who like OOP. The next nine chapters go over web stuff starting out with basic things like cookies, forms, and databases. Then the authors go into more advanced areas like session management, XML, automation and web services (REST, SOAP, Mail, FTP, LDAP, and DNS to name a few).
The next chapter [17] is on the topic of graphics. This is a cool chapter if you like to create dynamic images. Things like creating a button image on the fly, or generating charts. Graphics are great to have a knowledge of because everyone likes graphical presentation of data and this chapter can help you get there.
Chapter 18 is on security and encryption which I found rather helpful. No one wants there web application to be the link that allows data to be compromised, and this chapter deals with many of those problem areas. Chapter 19 covers localization, chapter 20 is on debugging and testing. The debugging section does a great job of getting a person setup with the tools they need to properly debug an application including creating your own exception class. This is an outstanding chapter that every programmer can appreciate since every application needs debugging.
The remaining chapters cover performance tuning, regular expressions, files, directories, command line PHP, PERL and PECL. Being a Perl guy I found it interesting to see how the authors utilized regular expressions in PHP. And the chapter on command-line PHP was outstanding; I thought the recipe for creating a PHP command shell was pretty cool.
CONCLUSION
--
This book is like having the answer key to most of the random questions a person comes up with when writing code. I found this book to be very useful, it will be one of those references that I keep close, and gets very little shelf time. It is a solid book. It is hard to say what parts I liked best because this is one of those books that you like and must have, but then as time goes on and you use it more and more its value grows. This is an excellent book and I would strongly recommend it the PHP users that want to move to the next level.PHP Cookbook: Solutions and Examples for PHP Programmers Overview
When it comes to creating dynamic web sites, the open source PHP language is red-hot property: used on more than 20 million web sites today, PHP is now more popular than Microsoft's ASP.NET technology.
