If you’re using PHP 4, then chances are good that an upgrade to PHP 5 is in your future. The more you’ve heard about the exciting new features in PHP 5, the sooner that upgrade is probably going to be. Although an in-depth, soup-to-nuts reference guide to the language is good to have on hand, it’s not the book an experienced PHP programmer needs to get started with the latest release. What you need is a lean and focused guide that answers your most pressing questions: what’s new with the technology, what’s different, and how do I make the best use of it? In other words, you need a copy of Upgrading to PHP 5. This book is targeted toward PHP developers who are already familiar with PHP 4. Rather than serve as a definitive guide to the entire language, the book zeroes in on PHP 5’s new features, and covers these features definitively. You’ll find a concise appraisal of the differences between PHP 4 and PHP 5, a detailed look at what’s new in this latest version, and you’ll see how PHP 5 improves on PHP 4 code. See PHP 4 and PHP 5 code side-by-side, to learn how the new features make it easier to solve common PHP problems. Each new feature is shown in code, helping you understand why it’s there, when to use it, and how it’s better than PHP 4. Short, sample programs are included throughout the book. Topics covered in Upgrading to PHP 5 include:
The new set of robust object-oriented programming features
An improved MySQL extension, supporting MySQL 4.1, prepared statements, and bound parameters
Completely rewritten support for XML: DOM, XSLT, SAX, and SimpleXML
Easy web services with SOAP
SQLite, an embedded database library bundled with PHP 5
Cleaner error handling with exceptions
Other new language features, such as iterators, streams, and more.

Upgrading to PHP 5 won’t make you wade through information you’ve covered before. Written by Adam Trachtenberg, coauthor of the popular PHP Cookbook, this book will take you straight into the heart of all that’s new in PHP 5. By the time you’ve finished, you’ll know PHP 5 in practice as well as in theory.

Over the past three years PHP has evolved from being a niche language used to add dynamic functionality to small sites to a powerful tool making strong inroads into large-scale, business-critical Web systems.

The rapid maturation of PHP has created a skeptical population of users from more traditional “enterprise” languages who question the readiness and ability of PHP to scale, as well as a large population of PHP developers without formal computer science backgrounds who have learned through the hands-on experimentation while developing small and midsize applications in PHP.

While there are many books on learning PHP and developing small applications with it, there is a serious lack of information on “scaling” PHP for large-scale, business-critical systems. Schlossnagle’s Advanced PHP Programming fills that void, demonstrating that PHP is ready for enterprise Web applications by showing the reader how to develop PHP-based applications for maximum performance, stability, and extensibility.

John Hagel III, Arthur G. Armstrong, “Net Gain: Expanding Markets Through Virtual Communities”
Publisher: Harvard Business School Press | 1997 | ISBN 0875847595 | PDF | 235 pages | 1.04 MB

Virtual communities are groups of people who share common interests and needs who come together on-line. Most are drawn by the opportunity to share a sense of community with like-minded strangers-regardless of where they live. But virtual communities are more than just a social phenomena: what starts off being a group drawn together by common interests ends up being a group with a critical mass of purchasing power-based in part on the fact that in communities, members can exchange information with each other on such things as a product’s price and quality.

Oleg Davydov, “Inside Out: The Radical Transformation of Russian Foreign Trade”
Publisher: Fordham University Press | 1998 | ISBN 0823218309 | PDF | 224 pages | 1.52 MB

Oleg Davydov’s Inside Out examines Russia’s foreign economic relations from 1992 to 1996, a period of drastic change and transformation. During these years, as it underwent the change from being a state monopoly to liberalism, Russia’s economy was rebuilt and the very principle of foreign trade redefined. After 1992, both industrial and agricultural enterprises in Russia were unchainedand received the right to trade freely without any permission from “the top.” Davydov studies the changing role of the government in Russia’s economy as it actively searches for new markets as well as seeks to integrate Russia’s economy into the world’s. These economic reforms, Davydov proposes, should result in the integration of the Commonwealth member countries, Russia’s admittance into the WTO, and the creation of a free trade zone with the EC all of which will provide tremendous opportunities for Russia as it embarks on the road of a sustained and democratic development.
