Steps to implement the product promotion discount label function in PHP Developer City
In today's development of e-commerce, product promotion strategy plays an important role. In many online shopping malls, in order to attract customers' attention, product promotion discount labels are increasingly used. How to implement the product promotion discount label function in a mall developed in PHP? The implementation steps will be described in detail below.
Step 1: Create a database table
First, create a product table in the database to store product information. Table fields can include product ID, product name, product price, discount price, etc., and can be designed according to actual needs. At the same time, you can also add a field to the table to save the promotion label information.
Step 2: Add promotion label field
In the product table, you need to add a field to save the promotion label information. You can use VARCHAR or ENUM types to store tag information. For example, the ENUM type can define some commonly used promotion tags, such as "limited time discount", "full discount", etc. Promotion tags can also be customized as needed.
Step 3: Write the product list page
In the mall developed by PHP, the product list page is very important. In this page, you can query the database to obtain product information and display it on the page. At this time, you can determine whether the promotion label needs to be displayed based on the product's promotion label field.
Step 4: Display the icon according to the promotion tag
According to the promotion tag field obtained from the product list page, the corresponding icon can be selected for display through conditional judgment. For example, if the promotion label field is "Limited Time Discount," add a "Limited Time Discount" icon next to the product name.
Step 5: Handle the click event of the promotion tag
In the mall, the user may click the promotion tag, hoping to view all products with that tag. In this step, you need to handle the click event of the promotion tag. You can filter by adding conditions to the database query to obtain all products with the promotion tag and display them on a new page.
Step 6: Update promotion tags regularly
Product promotion tags usually have a time limit and need to expire after a certain period of time. In mall development, promotion tags need to be updated regularly. You can achieve the purpose of updating by setting a scheduled task to set the promotion label field to empty after a specific time.
Summary:
Through the above steps, we can realize the product promotion discount label function in PHP Developer City. By creating a database table, adding a promotion tag field, and displaying corresponding icons based on the tag field, users can clearly understand product promotion information. At the same time, we also need to handle the event of clicking the promotion label to display all products with the promotion label. By regularly updating promotion tags, we ensure timely updates of promotional information and provide users with a better shopping experience.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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 originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.
