Enzyme is an architecture for creating user-searching-user applications. Right now, it is primarily useful as a resume create/search and HR management system. However, it's potential uses are wide-ranging, and it offers PHP developers an alternative to relying on simple "keyword" searching systems.
dynAdmin is a content management system (CMS) that is unlike any other. Most CMSes out there create dynamic Web sites that are based on news entries. dynAdmin creates dynamic Web sites based on individual sites, templates, and most important of all, pages. Besides allowing for dynamic Web sites in this way, it has many other features such as news generation automatic FAQs, completely customizable templates (both site-based and global), multiple users, printable pages, templates, and more.
C-Cramp (the C-Cramp College Radio Audio Management Program) is a Web-based frontend to MySQL for managing the types of things that small radio stations might need: audio files, data, and "metadata"; DJ and staff information, schedules, live music and program logs, and all sorts of other data. Currently, a cross-platform PHP application is the focus of the project, but more features and types of programs are planned that will hopefully enable easier playback, storage, loading, and entering for all types of applicable data.
