What are the steps to implement the takeaway delivery cost calculation function of PHP development ordering system?

With the continuous development of Internet technology, catering takeout business is becoming more and more popular. In order to improve the user experience, restaurants need to develop a complete ordering system, including a calculation function for takeaway delivery costs. This article mainly introduces the steps to implement takeaway delivery cost calculation in PHP development.

1. Requirements Analysis

Before developing the takeout delivery cost calculation function, it is necessary to complete the requirements analysis for this function. The specific requirements for calculating takeout delivery costs are as follows: Calculate the user's delivery address, and calculate the user's takeout delivery cost based on the restaurant's delivery policy. Under normal circumstances, the calculation of delivery costs requires reference to the following factors:

1. The distance between the restaurant and the user;
2. The price of the takeout order;
3. The number of delivery personnel and delivery distance; the minimum consumption amount set by the
4. restaurant.

Therefore, before development, detailed demand analysis and process design are required for the above factors.

2. Development environment and tools

When developing the takeout delivery cost calculation function, you need to master the following development environment and tools:

1. PHP development language;
2. Mysql database;
3. Apache or Nginx server;
4. PhpStorm and other PHP integrated development environments.

3. Technical Analysis

When realizing the takeout delivery cost calculation function, the following two technologies need to be used:

1. Geographical location positioning technology

When the user submits an order, the user's shipping address needs to be obtained. In order to accurately calculate the user's distance from the restaurant, geolocation technology needs to be used. Through the geographical location information, the distance between the user and the restaurant can be obtained, and whether it is within the service range of the restaurant.

2. Algorithm Optimization Technology

In the calculation of takeaway delivery costs, multiple factors need to be considered, and the priorities and influencing factors among multiple factors need to be considered. Algorithmic optimization techniques need to be utilized. Optimization algorithms will further shorten the running time of program code and optimize the calculation process.

4. Function implementation steps

Based on the above technology and demand analysis, the following are the steps to implement the takeaway delivery cost calculation function:

1. Get the user’s delivery address

Users need to fill in the shipping address when submitting an order. The background program needs to obtain the user's address information from the order information.

2. Geolocation Positioning

Use geolocation positioning technology to obtain the distance between the user and the restaurant and determine whether the user is within the service range of the restaurant. For users who are too far away, the background program needs to give prompt information, suggesting that users change restaurants or increase delivery fees.

3. Get the price of the order

Get the user's order price based on the order information.

4. Number of delivery persons and delivery distance

The delivery fee is calculated based on the number of delivery persons and delivery distance. The number of delivery persons and delivery distance will affect how delivery costs are calculated. For example, the delivery fee for a multi-person delivery order needs to be calculated based on the number of people, while the delivery fee for a single-person delivery order needs to be calculated based on the distance.

5. The delivery fee is calculated based on the minimum consumption amount set by the restaurant

The restaurant will generally set a minimum consumption amount. If the order amount is lower than this amount, it will be charged Additional delivery charges apply. The program needs to compare the order total and the minimum consumption amount to calculate the delivery fee that should be charged.

6. Return results

Return the calculation results to the front page and remind the user of the delivery fee that needs to be paid.

5. Summary

This article mainly introduces the steps to implement the takeout delivery cost calculation function of the PHP development ordering system. During the implementation process, detailed demand analysis and technical analysis are required, especially the use of geographical location positioning technology and algorithm optimization technology to achieve complete functions. Through the implementation of the above steps, the user experience can be improved, and the operating efficiency of the restaurant can also be effectively improved.
