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

1. 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.
2. 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.
3. 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

1. 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.
2. 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.
3. 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.
4. 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.
