Summary of ThinkPHP development experience: How to perform code refactoring and optimization

As a widely used PHP development framework, ThinkPHP brings many conveniences and excellent development experiences to programmers. In long-term development practice, we have continuously explored and summed up some experiences, one of which is code refactoring and optimization. This article will share some code refactoring and optimization experiences for ThinkPHP projects, hoping to be helpful to developers.

1. Review the code logic

Before refactoring the code, you first need to review the code logic, especially a comprehensive review and thinking of the entire project to identify possible problems in the project and bottlenecks. This can help us better understand the architecture and business logic of the entire project, and play an important guiding role in the subsequent reconstruction and optimization process.

2. Optimize SQL query statements

During the execution of the program, database operations are often one of the key factors affecting performance. Optimizing SQL query statements is one of the important means to improve program performance. In ThinkPHP, SQL query statements can be optimized by using cache and other methods. Turning on SQL cache can effectively improve program performance and reduce the burden on the database.

3. Avoid repeated queries

In the program, we may query the same data table multiple times, which will bring unnecessary load to the database and reduce the performance of the program. Therefore, when writing code, you should try to avoid repeatedly querying the data table. You can use caching technology to reduce the number of queries and improve performance.

4. Optimize the code structure

The code structure is clear and easy to maintain and update. Therefore, when we perform code reconstruction, we should pay special attention to the code structure. The code structure can be made clearer by encapsulating and refactoring functions, models, and controllers.

5. Avoid redundant file loading

During the development process, in order to facilitate debugging and development, we may introduce many unnecessary files. This not only reduces the performance of the program, but also takes up space on the server. Therefore, when refactoring the code, the files need to be streamlined to avoid redundant file loading.

6. Use caching technology

In ThinkPHP, caching technology is one of the commonly used optimization methods. Caching data in the cache can effectively improve program performance and reduce the burden on the server and database. When using cache, attention should be paid to optimizing cache time and storage methods.

7. Optimize template files

In ThinkPHP, template files are a key component in building views. Therefore, optimizing template files is also one of the important means to improve program performance. Static resource files can be separated to avoid repeated loading and reduce server pressure.

Summary:

The above is the ThinkPHP code reconstruction and optimization experience shared in this article. In the actual development process, we can also perform targeted optimization based on specific project needs to improve the maintainability and scalability of the project, optimize performance, and ultimately achieve efficient development and stable operation. I hope the above summary can be helpful to developers.
