Cody Caughlan has created a project that brings one of the popular features of Ruby on Rails to the world of PHP5 - database migrations.
One of the cool things I like about Ruby on Rails is the use of "migrations" for maintaining your DB. Migrations have proven to be pretty handy in keeping a local database in sync with the work of other developers. [...] Because migrations are incremental and they are done in a structured manner, it is a great way of pushing out new DB changes to the production database servers.
His framework, Ruckusing Migrations, is a modular framework that makes use of some of the more advanced features of PHP5. It's portable (via an adapter interface) and uses a generic task interface (task files) to load functionality into the framework. There's also plenty of API hooks to allow for a developer to easily create their own custom operations.
