Amfphp librairy “links” Flash and a server application.
For Püsh project, I’m going to use it to connect directy to database (by php). It’s faster and lighter than make your own xml exports.
With php you make MySql requests and Flash get results. Furthermore you can test your php file directly in a browser, without go in Flash, and you even make traces (thanks to NetDebug::trace(“”)).
For french speakers, an excellent book by Thibault Imbert (chapter 19 – Flash Remoting).
