Daniel Krook has a quick post about the DB2 driver he's created for the CakePHP framework:

I've just completed the initial version of the IBM DB2 interface that I've written for the CakePHP framework.

This driver can also be used with IBM Cloudscape, Apache Derby, and Sun Java DB because it employs the same ibm_db2 PECL extension for connecting to all of these RDBMSes.

Stay tuned to his blog for more details...
