php的amf和flex通讯有关问题

php的amf和flex通讯问题
这个例子中，为什么flex 调用的时候 不按顺序就出错，就是说PHP中的差别就是
require('D:/EmpireServer/ecshop/amfphp-2.1.1/Amfphp/Services/BaseAttribute.php');
语句出现的顺序。



edit_GetMaterialType_sq.php

class edit_GetMaterialType_sq
{
function IsLogin($isadmin)
{
	require('D:/EmpireServer/ecshop/amfphp-2.1.1/Amfphp/Services/BaseAttribute.php');
	$reLogin = array();
	$reLogin[] = 'IsLogin($isadmin)';
	return $reLogin;
}

function get_materialtype()
{
	$g = array();
	$g[] = 'materialtype()' ;
	return $g;
}

function get_templatetype($templateid,$userid)
{
	require('D:/EmpireServer/ecshop/amfphp-2.1.1/Amfphp/Services/BaseAttribute.php');
	$p = array();
	$p[] = 'get_templatetype' ;
	return $p ;
}
}
?>

BaseAttribute.php

class BaseAttribute
{
	var $Width = 0;
	var $Height = 0 ;
}
?>

在flex中这样调用测试的
example.mxml

			   xmlns:s="library://ns.adobe.com/flex/spark"
			   xmlns:halo="library://ns.adobe.com/flex/halo"
			   xmlns:mx="library://ns.adobe.com/flex/mx"
			   applicationComplete="application1_applicationCompleteHandler(event)">
	
	

					import mx.controls.Alert;
			import mx.events.FlexEvent;
			import mx.rpc.events.FaultEvent;
			import mx.rpc.events.ResultEvent;
			import mx.rpc.events.FaultEvent;
			import mx.rpc.remoting.RemoteObject; //RemoteObject,我认为相当于OLEDB的Connection，总的连接。
			
		
			
			protected  function application1_applicationCompleteHandler(event:FlexEvent):void 
			{
				// 在程序加载的时候运行该事件
              			so.IsLogin(true)                           //注意这三行的顺序，不这样就出错
				so.get_materialtype()                   //注意这三行的顺序，不这样就出错
				so.get_templatetype(1,1)           //注意这三行的顺序，不这样就出错

			}
			public function RemoteFaultss(re:FaultEvent,title:String):void	
			{		
				Alert.show("Message:" +re.fault.content+":"+re.fault.faultDetail,title);
			}
			public function IsLoginRemoteResultss(re:ResultEvent):void
			{ 		
				Alert.show( re.result.toString())
				
			}
			
			public function RemoteFault(re:FaultEvent,title:String):void	
			{		
				Alert.show("Message:" +re.fault.content+":"+re.fault.faultDetail,title);
			}
			public function IsLoginRemoteResult(re:ResultEvent):void
			{ 		
				Alert.show( re.result.toString())
					
			}
			protected  function button1_clickHandler(event:MouseEvent):void
			
			{
				
				// TODO Auto-generated method stub
				
				
				
			}
		
			public function RemoteFaults(re:FaultEvent,title:String):void	
			{

			}
			public function IsLoginRemoteResults(re:ResultEvent):void
			{

------解决方案--------------------
你的 BaseAttribute.php 文件中是一个类定义
重复加载是会出错的！
require('D:/EmpireServer/ecshop/amfphp-2.1.1/Amfphp/Services/BaseAttribute.php');
应放在外面，不能放在方法里
------解决方案--------------------
方法里会起冲突
