Flex and PHP with transaction support

I need to create an application that will use Flex on the client side and PHP on the server side. In my application I will need to have transactions opened for a long time (maybe 1, 2, 3 minutes). Can you give me any toughts on what PHP-FLEX fraework to use? I even found something like AS3FlexDB but it seem to not supporting transactions for a long ti开发者_运维问答me.

The library by your link is for connecting MySQL right from Flash client. As for me, your question isn't relevant to Flex but only related to PHP. Flex can produce client which can communicate with server using some protocol (XML or AMF using AMFPHP). But all the DB communication and transaction logic should be placed on a server (PHP) side. Flex client should be DB and transactions agnostic.
