PHP is a scripting language widely used in the field of Web development. In mall development, product classification display is a key function. Optimizing the product classification display function can improve user experience and increase shopping efficiency and convenience. This article will introduce the steps to optimize product classification display in PHP Developer City.
Step 1: Design the database table structure
In the PHP Developer City, product classification is a hierarchical structure. In order to realize the display and optimization of product classification, a reasonable database table structure needs to be designed. Generally speaking, two tables can be designed:
- Product classification table (category): including fields category_id (category ID), parent_id (parent category ID), category_name (category name), etc.
- Product table (product): includes fields product_id (product ID), category_id (category ID), product_name (product name), etc.
Step 2: Implement product classification display page
When developing a store with PHP, you need to create a product classification display page. This page can be implemented using technologies such as HTML, CSS and JavaScript. On the page, all product categories can be displayed in a tree structure, with product category names and links to specific product list pages displayed.
Step 3: Query and display product classification
Use PHP to write code and obtain product classification data through database query. You can query using SQL statements and store the results in an array. Then, by traversing the array, the product categories are displayed recursively. In the process of recursive display, it is necessary to determine the hierarchical relationship of each category and display the hierarchy in the correct indentation.
Step 4: Implement the expansion and folding functions of product categories
In order to improve the user experience, you can add expansion and folding functions to product categories. Users can click on a category to expand its subcategories, and click to collapse it again. You can use JavaScript to write code to achieve expansion and collapse effects by controlling the display and hiding of CSS styles.
Step 5: Optimize the loading speed of product classifications
In order to improve the loading speed of product classification pages, caching can be used to store classification data and reduce frequent queries to the database. You can use technologies such as Memcache or Redis to cache classified data in memory to improve page response speed.
Step 6: Implement product classification search
In the mall, users often need to search for products by product classification. In order to implement the product classification search function, you can add a search box to the page, write JavaScript code for the search box, and implement real-time classification search function through AJAX technology. Every time the user enters a keyword, they can request the backend interface through AJAX to obtain the corresponding product classification results and dynamically display them on the page.
Step 7: Add product classification filtering function
In the product list page, users often need to filter products by product classification. In order to implement the product classification filtering function, you can add one or more classification filter boxes on the page, and filter the products through PHP code according to the user's selection. You can query products that meet the classification filtering conditions by constructing SQL statements and display the results on the page.
Summary:
Through the implementation of the above steps, the function of product classification display optimization can be realized in the PHP Developer City. Optimized product classification display not only improves users' shopping experience, but also improves the efficiency and convenience of the mall. Through reasonable database design, appropriate front-end technology, and adding search and filtering functions, users can more easily find the products they need, improving user satisfaction and sales of the mall.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
