First let’s see the service:

<?php
// hello.php
class Hello
{
	public function sayHello()
	{
		return "Hello back!";
	}
}
 
?>

Now in Flex all we have to do is to load a XML file ( channel.xml ) and read the channel from it:

protected function addedToStageHandler( event :Event ) :void
{
 
	var loader :URLLoader = new URLLoader();
	loader.addEventListener( Event.COMPLETE, completeHandler );
	loader.addEventListener( IOErrorEvent.IO_ERROR, ioErrorHandler );
	loader.load( new URLRequest( "channel.xml" ));
 
}
 
protected function completeHandler( event :Event ) :void
{
 
	// Load info from XML
	var xml :XML = new XML( event.target.data );
	var amfEndpoint :String = xml..channel.( @id == "my-amfphp" ).@endpoint;
 
 
	// Create a AMF channel
	var channel :AMFChannel = new AMFChannel( "my-amf", amfEndpoint );
 
 
	// Add channel to our RemoteObject
	rmtObj.channelSet = new ChannelSet();
	rmtObj.channelSet.addChannel( channel );
 
}

Now if you use the loaded channel for all your RemoteObjects you don’t have to compile again your application if you decide to change your AMF endpoint, all you have to do is to edit the channel.xml file.

This is very useful when you upload your application to a server, you don’t have to compile again the application to work on different servers all you have to do is to use different channel.xml.

And this is all. If you have any questions post them here.
