Flex and php newbie question

Question

I have read on the adobe website that you could use php with flex.I know for applications to run on the desktop they have to be a .air format,like most tweeter desktop clients.I am therefore curious,wont one need things like apache and mysql for your app in php and flex or is everything transformed into a single .air including all your webserver.

Answer 1

The .air file contacts your webserver over their internet connection.

Answer 2

PHP is used for the backend only. The client is written in Flex. Both communicate via AMF. So yes, you need a webserver and network connection for this. See The architecture of Flex and PHP applications
