The Zend Developer Zone has (re)posted a tutorial from Kevin Schroeder about combining Flex and the Zend Framework to create a simple application. This is the first part in a series of articles on the subject.
Given that Zend has had a professional relationship with Adobe for a while, I have been looking for the time to actually dive into what Flash was offering so I could make some kind of judgment call on it. [...] With that in mind, I would like to talk about some introductory topics on what it would take to get a basic Flash/Flex application up and running. This will be part 1 of an X part series. I don't know how many parts there will be, but I would expect that there would be a few.
He walks you through the full process of using Flash Builder 4 (a 60 day free trial is available) and Zend Studio/Eclipse PDT to set up a native environment for rapid development of Flex apps. He creates the basic "Hello World" app, showing how to connect PHP to the Flex application and a bit of additional work to get it to cooperate with a MVCed Zend Framework application too.
