Question

我在Index.html上运行服务器并尝试注册时出现此类错误： Error Eclipse

如何解决此问题？我想创建一个简单的Web应用程序，可以在其中进行注册和登录。非常感谢这是我的代码：

        $value = hash( 'md5', time () . '21mondo13' );
        if ( setcookie( 'mycookie', $value, time() + 60*60*24*7 ) ) {
            $_COOKIE['mycookie'] = $value;
            echo 'cookie set';
        } else {

        }//if
    }//if
