The Aspect PHP Development Tools (APDT) project is a Eclipse platform based tool for AOSD in PHP. The goal is to deliver a user experience consistent with the PHP Development Tools (PDT) when working with PHPAspect projects and resources. The plugin provides an integration layer between the PHPAspect weaver, runtime and Eclipse/PDT extension points.
(from the projects website self-description)
APDT has superseeded phpaspect – Aspect-Oriented Programming for PHP.
