Best practices and expert techniques for today’s most demanding apps Expert PHP and MySQL ® www.it-ebooks.info Related Wrox Books Beginning PHP5, Apache, and MySQL Web Development ISBN: 978-0-7645-7966-0 PHP, Apache, and MySQL are the three key open source technologies that form the basis for most active web servers. This book guides you through the entire process of setting up your own site and walks you through every step, from the installation of PHP, Apache, and MySQL to database management, security, and integration with other technologies. The multi-platform approach addresses installation and usage on both Linux® and Windows®, and two common-themed, reusable web sites are examined. Upon completion of this book, you’ll be able to create well designed, dynamic web sites using open source tools. Beginning PHP 5.3 ISBN: 978-0-470-41396-8 As one of the most popular open-source web-programming languages in use today, PHP is an ideal server-side scripting language that connects HTML-based web pages to a backend database for dynamic content. It allows you to create anything from a simple form-to-email script to a web forum application, a blogging platform, or a content management system. This guide introduces the PHP language and shows you how to write powerful web applications using PHP. Professional PHP 5 ISBN: 978-0-7645-7282-1 This book has a pragmatic focus on how to use PHP in the larger scheme of enterprise-class software development. It covers UML modeling and presents objects and object hierarchies that, when completed, comprise a robust toolkit that developers will be able to reuse on future projects. This book is designed to arm you with the sort of constructs that are available out of the box with platforms such as Java and .NET — from simple utility classes like Collection and Iterator, to more complex constructs like Model/View/Controller architectures and state machines. Professional PHP Design Patterns ISBN: 978-0-470-49670-1 This book bridges the gap between the PHP and the older programming language by applying those tried and tested Design Patterns to native PHP applications. It starts with an introduction to Design Patterns, describes their use and importance, and details where you’ve seen them already. The book continues through a host of Design Patterns with code examples and explanations. Finally, an in-depth case study shows you how to plan your next application using Design Patterns, how to program those patterns in PHP, and how to revise and refactor an existing block of code using Design Patterns from the book. The author approaches the concepts in technical yet usable formats that are familiar to both programmers who are self-taught and those with more extensive formal education.
