There's >another great tutorial posted over at paranoidferret.com by Charlie Key. This one deals with sending and receiving data from a MySQL database using JSON to transfer the data.

Charlie Key, who runs the Paranoid Ferret blog, has written up a nice tutorial about using Flex and JavaScript together. These are especially useful for PHP developers who are looking to incrementally add Flex to their existing web applications.

His blog has a number of great Flex tutorials. Check them out.
