Talk given on 27th January 2012 at PHP Benelux 2012 conference in Antwerp, Belgium.

An insight into the Phing build system for PHP, why and how you might use it along with where it sits with related tools such as PHPUnit, PHP Code Sniffer, PHP Mess Detector etc. We will also take a brief look at how Phing can integrate with Continuous Integration, taking Jenkins as our example. We will also be including some simple practical demos of Phing in action!
