Multi-user blogging system implemented in PHP

Introduction:
With the development of the Internet, more and more people are beginning to use blogs to share their thoughts , knowledge and experience. In order to meet the needs of users, it is very important to develop a fully functional blog system. This article will introduce how to use PHP language to implement a multi-user blog system.

1. System requirements analysis
Before starting coding, we need to clearly understand the requirements of the blog system. A multi-user blog system should have the following functions:

1. User registration and login functions;
2. Users can publish blog posts;
3. Users can browse, comment and click Like other users' blog posts;
4. Users can edit and delete their own blog posts;
5. System management functions, including administrators can manage users, review blog posts, and delete them. Content that complies with regulations, etc.

2. Database design
We can use the MySQL database to store user information and blog post content.

1. User table (user): includes user ID, user name, password, email and other fields;
2. Article table (article): includes article ID, user ID, title, content , publishing time and other fields;
3. Comment table (comment): including comment ID, article ID, user ID, comment content, comment time and other fields.

3. Implementation of core functions

1. User registration and login functions
   User registration and login functions are the basis of the blog system. The following is a code example:

// 注册
function register($username, $password, $email) {
    //... 注册逻辑
    //... 将用户信息插入数据库
}

// 登录
function login($username, $password) {
    //... 登录逻辑
    //... 验证用户名和密码是否匹配
}

2. Publish blog articles
   After logging in, users can publish their own articles through the blog system. The following is a code example:

// 发布文章
function publishArticle($userId, $title, $content) {
    //... 发布文章逻辑
    //... 将文章信息插入数据库
}

3. Browse, comment and like functions
   Users can browse other users' blog posts, and comment and like. Here is a code example:

// 浏览文章
function viewArticle($articleId) {
    //... 获取文章信息
    //... 显示文章内容
    //... 显示评论列表
}

// 评论文章
function commentArticle($userId, $articleId, $content) {
    //... 评论文章逻辑
    //... 将评论信息插入数据库
}

// 点赞文章
function likeArticle($userId, $articleId) {
    //... 点赞逻辑
    //... 更新文章点赞数
}

4. Editing and deleting blog posts
   Users can edit and delete their own blog posts. The following is a code example:

// 编辑文章
function editArticle($articleId, $title, $content) {
    //... 编辑文章逻辑
    //... 更新文章信息
}

// 删除文章
function deleteArticle($articleId) {
    //... 删除文章逻辑
    //... 从数据库中删除文章信息
}

4. System management functions
Administrators can manage users, review blog posts and delete content that does not comply with regulations. These features require users with specific permissions to use.

5. Summary
In this article, we introduced how to use PHP language to implement a multi-user blog system. Through the user registration and login functions, users can publish, browse, comment and like blog posts. In addition, article editing and deletion functions and system management functions also provide users with more choices. Through this system, users can better share their ideas and experiences.

(Note: The above code examples are only for illustration, and the specific implementation needs to be adjusted and optimized according to the actual situation.)
