With another entry into the "PHP frameworks" category comes CodeIgniter, an "Open Source Web Application Framework that makes writing kick-ass PHP programs simple as apple pie".

Designed to enable, not overwhelm, Code Igniter is a powerful PHP/MySQL framework with a very small footprint, built for PHP coders who need a simple and elegant toolkit to create full-featured web applications.

If you're a developer who lives in the real world of shared hosting accounts and clients with deadlines, and if you're tired of ponderously large and thoroughly undocumented frameworks that require rocket science to understand, Code Igniter might just be the right tool for you.

They've released a beta (version 1.0) for public consumption, and it looks like it has promise. It has simplicity at its core, and makes it simple to build up useful apps quickly. Be sure to check out the videos of it in action...
