Implement PHP mall product delivery time calculation

Steps to implement the product delivery timeliness calculation function in PHP Developer City

With the rapid development of e-commerce, more and more consumers choose to shop online. During the shopping process, the delivery time of goods has become one of the important factors for consumers to choose to purchase. In the mall system developed by PHP, realizing the product delivery time calculation function can improve the user experience and better meet the needs of consumers. This article will introduce the specific implementation steps.

1. Data preparation
Before starting to implement the product delivery timeliness calculation function, we need to prepare some relevant data:

1. The transportation company’s delivery area and timeliness data;
2. The shipping address of the product and its corresponding delivery area.

2. Create database tables
Create two tables in the database, which are used to store the delivery area and timeliness data of the transportation company and the shipping address of the goods.

3. Write code to implement

1. Connect to the database
   Use PHP code to connect to the database and select the database to use.
2. Query the delivery area and timeliness data of the transportation company
   Use SQL query statements to obtain the delivery area and timeliness data of the transportation company and save it in an array.
3. Query the shipping address of the product
   Query the shipping address based on the product selected by the user, and match the shipping company's delivery area based on the address.
4. Calculate delivery timeliness
   Match the delivery area of the product selected by the user and the corresponding shipping address with the delivery area of the transportation company to obtain the corresponding delivery timeliness data.
5. Display delivery time
   Display the calculated delivery time data to the user.

4. Optimize implementation efficiency
In order to improve the operating efficiency of the program, we can store the transportation company's delivery area and timeliness data in the cache. Memory caching technologies such as Redis and Memcached can be used.

5. Test function
After completing the code writing, perform functional testing. Different products and shipping addresses can be simulated for testing to ensure the normal operation of the delivery time calculation function.

6. Optimize user experience
In order to improve the user experience, information related to product delivery timeliness can be displayed on the front-end interface, such as the name of the express company, delivery area, and estimated delivery time.

Summary:
Through the above steps, we can implement the product delivery time calculation function in the mall system developed in PHP. Such functional implementation not only improves the user experience, but also better meets consumers' needs for product delivery timeliness. At the same time, the mall system can also improve its competitiveness by optimizing efficiency and improving user experience.
