Core PHP Programming, Third Edition is the most authoritative guide to the new PHP5. Leading PHP developer Leon Atkinson and PHP5/Zend 2.0 co-creator Zeev Suraski cover every facet of real-world PHP5 development, taking students from basic syntax to advanced object-oriented development. Atkinson and Suraski cover networking, data structures, regular expressions, math, configuration, graphics, MySQL/PostgreSQL support, XML, algorithms, debugging, optimization, the Zend 2.0 engine, and much more. They also offer an authoritative introduction to PHP5 design patterns—including the popular Singleton, Factory and Observer design patterns—helping students discover today's best practices for building robust, efficient PHP5 code. Building on two previous editions, this book presents more than 650 downloadable examples—all reflecting the insights of the creators of the Zend Engine that drives high-performance PHP5 development. From start to finish, it has been carefully technically reviewed by PHP5 co-creator Andi Gutmans.
