WebORB for PHP Example in the PHP SDK by Adobe
Pete Mackie from Seaquest created an excellent example demonstrating remoting between Flex 2 clients and PHP Web server performing MySQL database I/O. The example is now a part of the open source PHP SDK by Adobe. You can read more about the example and get installation instructions here.
Here's an interesting conclusion Pete arrived at while working on the example:
"So far as I can tell, WebORB for PHP is the only Object Request Broker that properly handles and returns PHP exceptions properly. AMFPHP does return [object:Object] without a clue on how to handle the data"If anyone runs into any difficulties with the example or the product, feel free to post about it on the WebORB for PHP discussion forum.
