We are excited to announce the availability of our newest book:  Functional Programming in PHP by Simon Holywell.  PHP gained anonymous functions and closures in 5.3, which provided the basis allowing functional programming techniques to be used within PHP itself.  This book is designed to cover all aspects of Functional Programming in PHP and give you the core knowledge of this paradigm.

NOTE: We launched this book yesterday to our mailing list with a special sale of the 1st print run.  Within 12 hours we completely sold out of that print run and are producing more books as we speak!
