Sebastian Bergmann has pointed out the release of phpUnderControl by Manuel Picher - a tool to help with the integration of CruiseControl into your PHP project.
It integrates three of the best PHP development tools into CruiseControl, combined with an easy setup routine and a small example project.
Sebastian also points out that it can be used with the generated output of PHPUnit, the PHP_CodeSniffer package and the phpDocumentor utility.
You can find out more about phpUnderControl on its wiki page on the PHPUnit website.
