Best persistence practices in PHP API development

With the continuous development of the Internet, Web API is becoming more and more widely used as a means of communication between software systems, especially the development of PHP API, which is accepted by more and more developers due to its convenience and ease of use. However, during the development process, data persistence issues have always been a problem faced by many developers. This article will introduce the best persistence practices in PHP API development.

1. Common data persistence solutions

In the development of PHP API, common data persistence solutions include MySQL, MongoDB, Redis, Memcached, etc. Each of these solutions has advantages and disadvantages, and developers need to choose the appropriate solution based on the actual situation.

MySQL is the most commonly used relational database, supporting transactions and ACID features. MySQL is the best choice when dealing with large amounts of structured data and complex business logic. However, MySQL's read and write speed is relatively slow and is not suitable for high concurrency scenarios.

MongoDB is a document database that can store complex data structures. MongoDB is a worthy choice when dealing with unstructured data and requiring high availability and scalability. However, MongoDB's write performance is not as good as MySQL's and it lacks strict data consistency.

Redis is a memory-based cache database that can quickly read and write data. Redis is a very good choice when dealing with simple data that does not require persistence in a short period of time. However, Redis is not suitable for storing large amounts of data because it requires memory to store all the data.

Memcached is also a memory-based cache database, similar to Redis, and is very useful when processing simple data. However, unlike Redis, Memcached does not support disk persistence, so after restarting the server, all data will be lost.

2. Best Persistence Practices

After choosing a suitable data persistence solution, you need to consider how to best use them.

2.1 Choose the appropriate storage format

Storage format is an important factor affecting data storage and reading speed. When using MySQL or MongoDB, you can choose efficient storage formats such as JSON or MessagePack. For cache databases Redis and Memcached, using serialization and deserialization can improve the storage and reading speed of data.

2.2 Using cache

Cache is an important means to improve data access speed. Cache databases Redis and Memcached can read data quickly. During development, commonly used data can be stored in the cache and data can be read from the cache when needed, thereby increasing the execution speed of the application.

2.3 Optimizing database queries

Optimizing database queries can improve the execution speed of the application. When using MySQL, you can use indexes to speed up queries. When using MongoDB, you can use composite indexes to improve query speed.

2.4 Use database connection pool

Connection pool is a technology that reuses database connections, which can reduce the cost of establishing and closing connections in the database, thereby improving the execution speed of applications. In PHP API development, you can use connection pools to manage database connections and improve execution efficiency.

3. Conclusion

In the development of PHP API, the choice of data persistence scheme is crucial to the performance and stability of the application. Developers need to choose a suitable solution based on the actual situation and combine it with best persistence practices to improve application performance and stability.
