наверное так:

function senderData(id:Number, param:String, script:String):Boolean
{
	var sendLoader:URLLoader = new URLLoader();
	var sendRequest:URLRequest = new URLRequest('mydomen'+script+'.php' + '?' + Math.random());
	sendRequest.method = URLRequestMethod.POST;
	var sendVars :URLVariables = new URLVariables();
	sendVars['id'] = id;
	sendVars['param'] = param;
	sendRequest.data = sendVars;
	sendLoader.load(sendRequest);
	var resulter:Boolean = false;
	sendLoader.addEventListener(Event.COMPLETE, function(e:Event)
	{
		if (sendLoader.data == "ok")
		{
			resulter = true;
Poluchi();
		}
	});
	return resulter;
}
 
 
function Poluchi(){
trace(resulter);
}
