AS-AMFPHP AS和AMFPHP的数据交互

What's AMFPHP?官方的介绍如下：

AMFPHP is a free open-source PHP implementation of the Action Message Format(AMF). AMF allows for binary serialization of Action Script (AS2, AS3) native types and objects to be sent to server side services. AMFPHP is challenged with implementing the entire AMF protocol to be an alternative to Flex Data Services (AMF3) and Flash Remoting (AMF0). AMFPHP allows thin client applications built in languages such as Flash, Flex, and AIR to communicate directly with PHP class objects on the server. PHP developers can leverage their PHP experience in server side code development by connecting to data sources such as web-services, databases, and business applications and return that data to the client. Client applications can also offload cpu intensive methods to PHP services and wait for the result set for presentation to the user.......

官方的下载包虽然给了几个Demo，但是都没有操作数据库，刚好学习AMFPHP，做了个Demo，共享下，Demo如下：


下边是代码部分，先来AS的：

//flash跟amfphp通信的简单例子
package {
	import flash.display.MovieClip;
	import fl.events.*;
	import flash.events.*;
	import flash.text.TextField;

	import flash.net.NetConnection;
	import flash.net.Responder;

	public class Main extends MovieClip {
		private var gateway:String = "http://192.168.1.166/flashtest/as2php/amfphp/gateway.php";//amfphp gateway.php文件路径
		private var connection:NetConnection;
		private var responderSet:Responder;
		private var responderGet:Responder;

		public function Main() {
			//注册鼠标事件
			btnSet.addEventListener(MouseEvent.CLICK, setData);
			btnGet.addEventListener(MouseEvent.CLICK, getData);
			//设置responder
			responderSet = new Responder(onResultSet, onFault);
			responderGet = new Responder(onResultGet, onFault);
			connection = new NetConnection;
			//链接gateway
			connection.connect(gateway);
		}

		//发送数据给amfphp
		public function setData(_evt:MouseEvent):void {
			//获取输入框内的数据
			var info1 = txtInput1.text;
			var info2 = txtInput2.text;
			var info3 = txtInput3.text;
			//调用amfphp的函数
			connection.call("EasyAMF.setData", responderSet, info1,info2,info3);
			txtResponse.text = "Sending Data to AMFPHP";
		}

		//接收来自amfphp的数据
		public function getData(_evt:MouseEvent):void {
			connection.call("EasyAMF.getData",responderGet);
			txtResponse.text = "Geting data from AMFPHP";
		}

		//成功调用amfphp函数后的处理函数
		private function onResultSet(result:Object):void {
			txtResponse.text = String(result);
		}

		private function onResultGet(result:Object):void {
			var aryRs:Array=new Array();  //用一个数组来接收返回的记录
            aryRs=result["serverInfo"]["initialData"]; //从数据库中传来的值为何是2维数据其实我也没去看，google来的资料上说这么写～。～
			rsinput1.text=aryRs[0][1]; //显示数据
			rsinput2.text=aryRs[0][2];
			rsinput3.text=aryRs[0][3];
		}

		//调用amfphp函数失败后的处理函数
		private function onFault(fault:Object):void {
			txtResponse.text = String(fault.description);
		}
	}
}

接着是amfphp/services/EasyAMF.php，这部分是简单的SQL语句，就不写注释了：

< ?php
class EasyAMF
{
	public function EasyAMF(){

		 global $host,$dbTable, $dbPass,$dbId;
		 $host = "localhost";
		 $dbId = "root";
		 $dbPass = "";
		 $dbTable = "amfphp";

		 $dblink = mysql_connect($host,$dbId,$dbPass);
		 mysql_select_db($dbTable);
		 mysql_query("SET NAMES UTF8");
		 if(!$dblink)
		 {
				 die('Connection Impossible:' . mysql_error());
		 }
	}
    public function setData($info1,$info2,$info3)
    {
		 $sql="INSERT INTO info (id ,info1 ,info2 ,info3)VALUES (NULL , '$info1', '$info2', '$info3');";
		 $rs=mysql_query($sql);
		 if(!$rs==1){
			return "failed";
		 }else{
			return "success";
		 }
    }
	public function getData()
    {
         $sql="SELECT * FROM info ORDER BY id DESC LIMIT 1";
		 $rs=mysql_query($sql);
		 return $rs;
    }
}
?>

原先在做留言板的时候是准备用Ajax来进行数据交互，不过有了AMFPHP后，就没这个想法了。
