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:
- The distance between the restaurant and the user;
- The price of the takeout order;
- The number of delivery personnel and delivery distance; the minimum consumption amount set by the
- 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:
- PHP development language;
- Mysql database;
- Apache or Nginx server;
- 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:
- 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.
- 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:
- 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.
- 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.
- Get the price of the order
Get the user's order price based on the order information.
- 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.
- 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.
- 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.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
