复制代码 代码如下:

            die("请输入用户名!"); 
        }

        $user = "root"; 
        $pass = "zq19890319"; 
        $db = "cookie"; 
        //打开连接 
        $connection = mysql_connect($host, $user, $pass) or die("Unable to connect!"); 
        //选择一个数据库 
        mysql_select_db($db) or die("Unable to select database!"); 
        //建立一个查询 
        $query = "SELECT * FROM users WHERE name = '".$_POST['name']."' AND pass = SHA1('".$_POST['pass']."')"; 
        //执行一个查询 
        $result = mysql_query($query) or die("Error in query:$query." . mysql_error()); 
        //是否有记录集返回 
        if(mysql_num_rows($result) == 1){ 
            //如果有一行记录返回 
            //表示验证已经通过 
            //建立一个session,设置一个登陆标记为1,并将当前用户名保存在cookie中 
            session_start(); 
            $_SESSION['auth'] = 1; 
            setcookie("username", $_POST['name'], time()+(84600*30)); 
            echo "用户访问已经授权!"; 
        }else{ 
            echo "错误的用户名或密码!"; 
        }
