Implementation method of order delivery route planning function for developing food shopping system using PHP

With the development of the Internet and mobile technology, online shopping has become a part of people's lives. Daily grocery shopping services have also gradually moved online, making people's lives more convenient. However, for a grocery shopping system, implementing the order delivery route planning function is a very important task. This article will introduce the implementation method of using PHP to develop the order delivery route planning function of the grocery shopping system.

1. Requirements analysis
Before starting development, we need to conduct needs analysis. The order delivery route planning function of the grocery shopping system mainly has the following demand points:

1. Enter order information: including order number, delivery address, delivery time, etc.
2. Calculate the optimal delivery route based on order information: By calling the map API, the order information and the location information of the delivery person and user are passed to the API, and the API returns the optimal delivery route.
3. Display delivery route: Display the optimal delivery route on the map, and also display the delivery person's location and real-time delivery progress.

2. Technology selection
When developing the order delivery route planning function of the grocery shopping system, we chose to use PHP language for development. PHP is a server-side scripting language that is ideal for developing web applications. At the same time, we need to use map API to calculate the optimal delivery route. Commonly used map APIs include Baidu Map API, Amap API, etc.

3. Implementation steps

1. Database design: We first need to design the database table structure. The order table includes fields such as order number, shipping address, delivery time, etc. The user table and delivery person table include fields such as user/delivery person name, mobile phone number, longitude and latitude.
2. Map API access: First, we need to register a developer account on the map API platform and obtain the API key. The API key is then embedded into the system for subsequent calls. Next, we can call the route planning service provided by the map API through the interface, pass the order information and the location information of the user and delivery person to the API, and obtain the optimal delivery route.
3. Interface design: Design the delivery route planning interface of the grocery shopping system to display order information, delivery person location and real-time delivery progress. Interface design can be completed using HTML, CSS and JavaScript.
4. Back-end development: Use PHP language to develop back-end code, including input of order information, call of map API and display of optimal delivery route. You can use PHP frameworks such as Laravel to simplify the development process and improve development efficiency.
5. Front-end development: Use HTML, CSS and JavaScript to develop front-end code, including input of order information and display of delivery routes. You can use front-end frameworks such as jQuery to simplify the development process and improve user experience.

4. Testing and Deployment
After completing the development, we need to test the order delivery route planning function of the grocery shopping system to ensure the stability and reliability of the function. At the same time, we need to deploy the system to the server so that users can access and use it normally.

5. Summary
Through the above steps, we can use PHP to develop the order delivery route planning function of the grocery shopping system. This function can help merchants quickly plan delivery routes, improve delivery efficiency, and also facilitate users to check delivery progress. During the actual development process, some functions can be expanded and optimized according to needs to improve user experience. Developing an efficient and stable grocery shopping system can provide users with a better shopping experience and promote the development of online grocery shopping services.
