Advanced PHP Programming (repost)

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