出现界面，不错
但是按按钮，就报错：

Fatal error: Call to a member function Add() on a non-object in 从c:\dir\Delphi for PHP Projects\test01\unit1.php on line 20

代码：
<?php
//Includes
require_once("vcl/vcl.inc.php");
use_unit("menus.inc.php");
use_unit("forms.inc.php");
use_unit("extctrls.inc.php");
use_unit("stdctrls.inc.php");

//Class definition
class Unit1 extends Page
{
public $Button1 = null;
public $Edit1 = null;
public $Memo1 = null;
public $Label1 = null;
public $MainMenu1 = null;
function Button1Click($sender, $params)
{

$Memo1->$Lines->Add($Edit1->$Text); //就是这一行报错。。。。

}


}

global $application;

global $Unit1;

//Creates the form
$Unit1=new Unit1($application);

//Read from resource file
$Unit1->loadResource(__FILE__);

//Shows the form
$Unit1->show();

?>
