In his latest blog post, Mike Potter shares some about a simple Flex application he's constructed that's now contained in the PHP RIA SDK from Adobe.
I have created a sample Flex application that lets you browse your MySQL databases and allows you to do simple filtering on that data. The application is part of the PHP RIA SDK by Adobe that I've updated today. It also includes some new samples and libraries, mostly done by community members.
He notes that it's not meant to be a replacement for things like phpMyAdmin, but it does have its place.
