How to use AMFPHP Objects in Flex

Question

Hi,
I have been successful in getting amfphp to return PHP objects, the question now is how can I make Flex aware of the objects?
I am invoking a remote object and the objects are returned as a result. Can they be used directly or should I use XML?

Hmm, your code seems a bit to complicated. Here's what I do:
The RemoteObject:
<mx:RemoteObject id="PHPGateway" source="yourAMFPHPClassName.ThePHPFile" destination="amfphp" showBusyCursor="true">
    <mx:method name="theFunctionYouWantToCall" result="myFunctionResultHandler(event)" fault="myFunctionFaultHandler(event)"/>
</mx:RemoteObject>
Observations:
1. yourAMFPHPClassName is the name of the folder in amfphp\services that contains the PHP classes.
2. ThePHPFile is the PHP class file (without the extension) in the yourAMFPHPClassName folder.
3. You need the <mx:method name="..." .../> to define the function in the PHP class you want  to call. The theFunctionYouWantToCall must be the exact name of the function in the PHP class (case sensitive).
The ActionScript part:
//THE BELOW EXAMPLE ONLY WORKS IF THE PHP FUNCTION RETURNS A SINGLE VALUE
//This means the PHP function has a return statement like this: return $value; or return "Test";
private function myFunctionResultHandler(event:ResultEvent):void
var PHPResult:String=String(event.result);
Alert.show(PHPResult);//will show what the PHP class returned
//THE BELOW EXAMPLE SHOWS HOW TO PASS MULTIPLE DATA TO FLEX
//This means the PHP function has a return statement like this:
//$returnValue=array();
//$returnValue['name']="George";
//$returnValue['age']=$age;
//return $returnValue;
private function myFunctionResultHandler(event:ResultEvent):void
Alert.show("Name: "+event.result.name);
Alert.show("Age: "+event.result.age);
//THE FAULT HANDLER
private function myFunctionFaultHandler(event:FaultEvent):void
Alert.show("Data could not be acquired.");
