使用变量将动作脚本3嵌入到flash中

Question

我有这个代码正常工作，但我需要将视频ID作为变量从php（取自数据库）中传递出来：

AS3代码：

package test_fla
{
import fl.controls.*;
import flash.display.*;
import flash.events.*;
import flash.net.*;
import flash.system.*;

dynamic public class MainTimeline extends MovieClip
{
    public var pause_btn:Button;
    public var play_btn:Button;
    public var my_player:Object;
    public var my_loader:Loader;

    public function MainTimeline()
    {
        addFrameScript(0, this.frame1);
        this.__setProp_pause_btn_Scene1_Layer1_0();
        this.__setProp_play_btn_Scene1_Layer1_0();
        return;
    }// end function

    public function onLoaderInit(param1:Event) : void
    {
        addChild(this.my_loader);
        this.my_player = this.my_loader.content;
        this.my_player.addEventListener("onReady", this.onPlayerReady);
        return;
    }// end function

    public function onPlayerReady(param1:Event) : void
    {
        this.my_player.x = 30;
        this.my_player.setSize(640, 360);
        this.my_player.cueVideoById("xEPBcJtd11A", 0, "small");
        return;
    }// end function

    public function playVid(param1:MouseEvent) : void
    {
        this.my_player.playVideo();
        return;
    }// end function

    public function pauseVid(param1:MouseEvent) : void
    {
        this.my_player.pauseVideo();
        return;
    }// end function

    function __setProp_pause_btn_Scene1_Layer1_0()
    {
        try
        {
            this.pause_btn["componentInspectorSetting"] = true;
        }// end try
        catch (e:Error)
        {
        }// end catch
        this.pause_btn.emphasized = false;
        this.pause_btn.enabled = true;
        this.pause_btn.label = "Pausa";
        this.pause_btn.labelPlacement = "right";
        this.pause_btn.selected = false;
        this.pause_btn.toggle = false;
        this.pause_btn.visible = true;
        try
        {
            this.pause_btn["componentInspectorSetting"] = false;
        }// end try
        catch (e:Error)
        {
        }// end catch
        return;
    }// end function

    function __setProp_play_btn_Scene1_Layer1_0()
    {
        try
        {
            this.play_btn["componentInspectorSetting"] = true;
        }// end try
        catch (e:Error)
        {
        }// end catch
        this.play_btn.emphasized = false;
        this.play_btn.enabled = true;
        this.play_btn.label = "Play";
        this.play_btn.labelPlacement = "right";
        this.play_btn.selected = false;
        this.play_btn.toggle = false;
        this.play_btn.visible = true;
        try
        {
            this.play_btn["componentInspectorSetting"] = false;
        }// end try
        catch (e:Error)
        {
        }// end catch
        return;
    }// end function

    function frame1()
    {
        Security.allowDomain("www.youtube.com");
        this.my_loader = new Loader();
        this.my_loader.load(new URLRequest("http://www.youtube.com/apiplayer?version=3"));
        this.my_loader.contentLoaderInfo.addEventListener(Event.INIT, this.onLoaderInit);
        this.play_btn.addEventListener(MouseEvent.CLICK, this.playVid);
        this.pause_btn.addEventListener(MouseEvent.CLICK, this.pauseVid);
        return;
    }// end function

}

}

那么，你会如何做同样的事情但传递一个php变量作为视频id而不是this.my_player.cueVideoById（＆＃34; xEPBcJtd11A ＆＃34;，0，＆＃34 ;小＆＃34）;直接？

谢谢!!!
