discuz通过调用函数实现同步登录与退出

//退出Discuz账号
	function discuz_logout(){
		require './bbs/source/class/class_core.php';	//引入系统核心文件  
	
		$discuz = & discuz_core::instance();				//以下代码为创建及初始化对象 
		$discuz->cachelist = $cachelist; 
		$discuz->init();
		

		require libfile('function/member');
		require libfile('class/member');
		
		$_GET['formhash'] = $_G['formhash'];
		
		
		$ctl_obj = new logging_ctl();
		$ctl_obj->setting = $_G['setting'];
		$method = 'on_logout';
		//$ctl_obj->template = 'member/login';
		$ctl_obj->$method();
		
		echo "成功退出！".time();	
	}
	
	//登录Discuz账号
	function discuz_login($username,$password){
		require 'E:/ku25.com/wwwroot/bbs/source/class/class_core.php';	//引入系统核心文件  
	
		$discuz = & discuz_core::instance();				//以下代码为创建及初始化对象 
		$discuz->cachelist = $cachelist; 
		$discuz->init();
		
		require libfile('function/member');
		require libfile('class/member');
		
		$_GET['formhash'] = $_G['formhash'];
		
		$_GET['from'] = 1;
		$_GET['loginsubmit'] = $_GET['infloat'] = 'yes';
		$_GET['cookietime'] = '2592000';
		
		$_GET['username'] = $username;
		$_GET['password'] = $password;
		
		$ctl_obj = new logging_ctl();
		$ctl_obj->setting = $_G['setting'];
		$method = 'on_login';
		//$ctl_obj->template = 'member/login';
		$ctl_obj->$method();
		echo "成功登录！".time();
