"Jenkins is a recent fork of another continuous integration
project named Hudson.) Although a Java-based solution, an active
plugin community has made it possible to use Jenkins for far more
than Java-specific projects. More recently it has become much
easier for Jenkins' novices to use the project in conjunction with
PHP projects thanks to the work of Sebastian Bergmann.
"Known as Template for Jenkins Jobs for PHP Projects, the
project provides a configuration file which you'll use to enable
Jenkins/PHP integration, and supports several popular familiar PHP
tools such as PHP_CodeSniffer and PHPUnit. In this article I'll
introduce you to just a few of the great ways you can begin using
Jenkins in conjunction with your future PHP projects."
