如何从PHP数据返回填充MXML Flex mx：List（使用actionscript和PHP）

Question

I am Using Flex 3 and apache with PHP 5.2.

I am searching for simple as possible way to fill my mx:List with data using POST URLRequest.

In Flex builder I am using the next code

public var variables_se:URLVariables = new URLVariables();
public var varSend_se:URLRequest = new URLRequest("DataProvider.php");
public var varLoader_se:URLLoader = new URLLoader;

public function starter():void
{
varSend_se.method = URLRequestMethod.POST;
varSend_se.data = variables_se;
varLoader_se.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoader_se.addEventListener(Event.COMPLETE, completeHandler_se);
variables_se.CountOflistItemsIWant = 30;
varLoader_se.load(varSend_se);
}

public function completeHandler_se(event:Event):void
{
    textFild.text += " " + String(event.target.data) + ";"; // any result will apear in some textFild
// How to make result appear as list lines, how to form PHP answer and AS3 code for it?
}

How to make result appear as list lines, how to form PHP answer and AS3 code for it (If for example I want to return random numbers from PHP in desired in CountOflistItemsIWant cuatety)?

Maybe you could make your php script echo json encoded array like so:

<?php
echo json_encode(array('first', 'second', 'foo', 'bar'));

and in flex get it, decode it and use it as argument for array data provider for your mx:List

You can find information about communicating between php and flex with use of json here: http://www.adobe.com/devnet/flex/articles/flex_php_json.html
