Smart web developers will tell you that the sooner you detect your code mistakes, the quicker you can fix them, and the less the project will cost in the long run. Well, the most efficient way to detect your mistakes in PHP is with PHPUnit, an open source framework that automates unit testing by running a battery of tests as you go. The benefits of PHPUnit are significant: a reduction in the effort required to frequently test code fewer overall defects added confidence in your code improved relations with your open source teammates The only problem with this popular testing tool was its lack of documentation-until now, that is. For this, O'Reilly went right to the source, as Sebastian Bergmann, the author of PHPUnit Pocket Guide, also happens to be PHPUnit's creator. This little book brings together hard-to-remember information, syntax, and rules for working with PHPUnit. It also delivers the insight and sage advice that can only come from the technology's creator. Coverage of testing under agile methodologies and Extreme Programming (XP) is also included. The latest in O'Reilly's series of handy Pocket Guides, this quick-reference book puts all the answers are right at your fingertips. It's an invaluable companion for anyone interested in testing the PHP code they write for web applications.

A collection of over 250 PHP functions with clear explanations in language anyone can understand, followed with as many examples as it takes to understand what the function does and how it works. This book includes numerous additional tips, the basics of PHP, MySQL query examples, regular expressions syntax, and two indexes to help you find information faster: a common language index and a function index. When the internet is not around or you want a simpler explanation along with all the technical details, this book has all of that and more.

The HyperText Transfer Protocol, or HTTP, is the backbone of the World Wide Web. HTTP is the language that each web browser (or other web client) uses to communicate with servers around the world. All web programmers, administrators, and application developers need to be familiar with HTTP in order to work effectively.The HTTP Pocket Reference not only provides a solid conceptual foundation of HTTP, it also serves as a quick reference to each of the headers and status codes that comprise an HTTP transaction. The book starts with a tutorial of HTTP, but then explains the client request and server responses in more detail, and gives a thorough technical explanation of more advanced features of HTTP (such as persistent connections and caching).Most people use the Web every day without knowing anything about HTTP, but for those who need to get "beyond the browser," this book is the place to start.

JavaScript--the powerful, object-based scripting language that can be embedded directly into HTML pages--has earned its place in the web developer's toolkit, to the extent that it's now considered required knowledge for web developers. You can use JavaScript to create dynamic, interactive applications that run completely within a web browser. JavaScript is also the language of choice for developing Dynamic HTML content. Because its syntax is based on the popular programming languages C, C++, and Java, JavaScript is familiar and easy to learn for experienced programmers. At the same time, it's an interpreted scripting language, providing a flexible, forgiving programming environment for new programmers. The JavaScript Pocket Reference, 2nd Edition, provides a complete overview of the core JavaScript language and client-side scripting environment, as well as quick-reference material on core and client-side objects, methods, and properties. The new edition has been revised to cover JavaScript 1.5, and is particularly useful for developers working with the standards-compliant web browsers, such as Internet Explorer 6, Netscape 7, and Mozilla. Ideal as an introduction for beginners and a quick reference for advanced developers, this pocket-sized book is easy to take anywhere and serves as the perfect companion volume to the bestselling JavaScript: The Definitive Guide, 4th Edition. O'Reilly's Pocket References have become a favorite among developers everywhere. By providing a wealth of important details in a concise, well-organized format, these handy books deliver just what you need to complete the task at hand. When you've reached a sticking point and need to get to the answer quickly, the new JavaScript Pocket Reference is the book you'll want close at hand.
