Architectural design and PHP code implementation of the mall SKU management module
1. Introduction
With the rapid development of e-commerce, the scale and complexity of the mall have also increasing day by day. The SKU (Stock Keeping Unit) management module of the mall is one of the core modules of the mall and is responsible for managing the inventory, price, attributes and other information of the products. This article will introduce the architectural design and PHP code implementation of the mall SKU management module.
2. Architecture design
- Database design
The database design of the SKU management module is the foundation of the entire architecture. The SKU management module of the mall usually includes product information table, attribute table, attribute value table, SKU table, etc. Among them, the product information table stores the basic information of the product, such as product name, product number, brand, etc.; the attribute table stores the attribute information of the product, such as color, size, etc.; the attribute value table stores the values corresponding to the attributes, such as red, blue, etc. ;The SKU table stores the specific SKU information of the product, such as inventory, price, etc. The design of the database should meet actual business needs and ensure data integrity and consistency. - Module Design
The design of the mall SKU management module can adopt the MVC (Model-View-Controller) mode. Among them, the model is responsible for processing data logic, including query, modification, deletion and other operations; the view is responsible for displaying data and user interaction interface; the controller is responsible for receiving user requests and calling the model and view for processing. Such a design can make the code structure clearer and easier to maintain and expand. - API Design
The mall SKU management module generally provides a series of API interfaces for other modules to call. APIs should be designed with security, performance, and scalability in mind. The API can be designed in RESTful style and operated using standard HTTP request methods (such as GET, POST, PUT, DELETE). In addition, the parameter design of the API should be reasonable, and the return results of the interface should be clear and easy to understand.
3. PHP code implementation
- Database connection
In the PHP code, you first need to establish a connection with the database. This can be done using database operation extensions such as PDO or mysqli. Through the database connection, you can execute SQL statements, query and modify the data in the database. - Model design
In the model of the SKU management module, a series of methods need to be implemented to complete the addition, deletion, checking and modification of data. For example, you can implement a method to query the inventory information of goods, obtain the corresponding data through database query statements, and return it to the controller. In addition, other operations need to be implemented, such as modifying product prices, deleting product SKUs, etc. - View Design
In views, user interfaces can be built through technologies such as HTML, CSS, and JavaScript. For example, you can design a product list page to display product name, price, inventory and other information. Users can perform operations on the page, such as modifying prices, adding inventory, etc. - Controller design
The controller is responsible for receiving user requests and calling models and views for processing. You can design a unified entry file and call different controller methods to process according to different requests. For example, when the user requests to query product inventory information, the controller can call the query method in the model to obtain the results, and pass the results to the view for display.
4. Summary
The architectural design and PHP code implementation of the mall SKU management module are important components of the mall. Through reasonable database design, module design and API design, an efficient, safe and scalable SKU management module can be realized. Through reasonable PHP code implementation, the mall system can be quickly developed and easily maintained and expanded. I hope this article will be helpful in understanding the architectural design and PHP code implementation of the mall SKU management module.

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
