I recommend you take a serious look at ColdFusion . Here is an Adobe site that talks the features and benefits of building RIAs with Adobe Flex/ColdFusion. http://www.adobe.com/devnet/flex/flex_cf.html
It is clearly the best fit promoted by Adobe. Adobe does a lot of work to bring Flex and CF together, such as out-of-the-flex support within CF. I agree. Any software language can meet any requirement. But, from my 20 years of doing/managing development in many different server technologies ... CF is by far the fastest to train, learn and implement rapidly. Since you know php, adding CF to your skill set will be any easy route to take. After all, ColdFusion is Java....just a heck of a lot easier. Good thing that Flex is Flexible and you can choose. I have some Flex apps that use CF, .Net, and Java on the back-end ... since in a Web 2.0/SOA architecture ... you can have many backends to a single Flex app. ... and the end user doesn't care what "shop" or "camp" your technology religion is anyway. :) Give CF a try. It will only take you a day to have your first Flex/CF app up and running! Don Kerr --- In [email protected], "bsyyu" <ben.s...@...> wrote: > > currently, I am using PHP as server language.
