复制内容到剪贴板
//该文档保存为login.php
//首先将接口技术文档里的加密解密函数拷贝
//为了不让代码太乱,我拷贝到文档的结尾处
//假设自己的用户数据库表里用户名字段为UserName, 密码字段为Pwd, Email字段为 Email
//注册页实现方法差不多,可自行实现,疑问加我QQ:2666556
$act=(isset($_GET['act']))?$_GET['act']:"login";
if(function_exists($act)) $act();else login();

if($ErrMsg!="")echo $ErrMsg;
//后面加上显示你的登陆表单的代码 如
?>
}//end function
function logout()//登出

//===========验证输入=====================

//=========数据库处理==========================
