很想知道高维空间是怎样的
物理学认为高维坍缩成小尺度了 是什么意思 理解不了?
还有就是二元方程用平面 三元方程可以用立体
多元方程怎么用几何表示?
有人说人类的大脑是三维结构的无法想象出四维,这有什么关系嘛?理解不了
还有生活中有没有体现高维的东西?
我说:

0. 教学是线性的(书是字符 一维的, 老师讲课 一维的, 文章一维的)
1. 人类智商低 (初中 教学只能教到二维)
2. 学的不够(在高中期间 大量的升维 思维练习 , 数字化, 抽象化 )(楼主在这里掉队了)
3. 知识被垄断了( 大学学习的高数 可以简单把三维变方程,用方程变换 来进行思考, 线数把方程 维度无限推高) ;
再看一下下面的代码..............
基本是如何接手这样的代码呢?
$goods = M("SightGoods")->field('id')->where(array('sight_id'=>$id))->select(); if($goods){ $ids = array(); foreach ($goods as $v) { $ids[] = $v['id']; } if(count($ids) > 0){ $orderWhere['gid'] = array('in',$ids); $orderWhere['comment_status'] = 2; $orderWhere['goods_type'] = 'sight'; $orders = D('SightOrderView')->field('id')->where($orderWhere)->select(); if($orders){ $oids = array(); foreach ($orders as $v) { $oids[] = $v['id']; } if(count($oids) > 0){ $page = $page-1; $pageCount = 10; $limit = $page*$pageCount.",".$pageCount; $comment = M('OrdersComment')->where(array('oid'=>array('in',$oids)))->limit($limit)->order('create_time DESC')->select(); if($comment){ foreach ($comment as &$v) { $user = M('Users')->field('mobile,openid,nickname,email,img,sex,ind_signature')->find($v['uid']);$user['img'] = $this->eve->arrangeUserImgPath($user['img']); $v['user'] = $user; $imgs = M('UserAlbum')->field('image_path')->where(array('obj_id'=>$v['id'],'image_type'=>1))->select(); $images = array(); if($imgs){ foreach ($imgs as $img) { $images[] = $this->eve->arrangeUserImgPath($img['image_path']); } } $v['images'] = $images; } $this->apiRetrun(1,'ok',$comment); } } } } } $this->apiRetrun(0,'no data'); }
这是一个人类典型的多维度思考方式的自然体现
我要说的是学习编程的人应该用升维练习来解读

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
