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.
