With the rapid development of Internet technology and the growing application needs, PHP's application scenarios are becoming more and more extensive. However, in scenarios such as high concurrency, massive data, and complex interactions, traditional PHP programming methods can no longer meet development needs. The microservice architecture has become an effective way to improve system performance and maintainability.
PHP programming based on microservice architecture
Microservice architecture (Microservice Architecture) is a service-oriented software architecture design method, which divides the application into multiple independent small ones according to business functions. Services, each service works together with each other through a light communication mechanism, and ultimately provides a complete service system. Compared with traditional monolithic architecture, microservice architecture has better scalability, flexibility, maintainability and reliability.
In PHP programming, the microservice architecture can be implemented using RESTful API interfaces to make services independent and composable. Common implementation methods include Laravel and Slim frameworks. The Laravel framework provides a concise and elegant RESTful API implementation that can easily create, publish and track microservices. At the same time, Laracon has also launched some useful tools, such as Lumen framework, DingoAPI and JWT, to make the implementation of microservices easier and more convenient.
When building a microservice architecture, you need to pay attention to the collaboration, communication and monitoring between microservices. Generally speaking, you can use some open source frameworks, such as Zipkin, Eureka, Ribbon, and Hystrix, to implement functions such as service discovery, load balancing, and circuit breakers. At the same time, it is also very important to pay attention to the monitoring and tracking of microservices. You can use components such as Prometheus and Grafana for real-time monitoring and data visualization.
Database Optimization Practice
Under the traditional PHP programming method, database design and optimization are often ignored, resulting in problems such as large amounts of data, complex queries, and slow response. In the microservice architecture, database optimization is even more important because it involves data interaction between multiple microservices.
The following are some common database optimization practice tips:
- Vertical split of database
Vertical split of database refers to splitting a large database into several small databases. In this way, each small database only contains data from a certain domain model, which can reduce data redundancy and the number of associated queries, and improve query efficiency. At the same time, it can also increase the scalability and maintainability of the system.
- Index optimization
Index is one of the important factors to improve query efficiency. When using indexes, you need to ensure that each query contains an available index. At the same time, you should avoid using too many indexes, because too many indexes will take up too much storage space and reduce write performance.
- Caching technology
Cache technology can keep frequently queried data in memory and reduce the number of accesses to the database. Common caching technologies include Redis, Memcached, APCU, etc.
- Read and write separation
Read and write separation refers to separating read and write operations into different databases to improve the performance of concurrent reading and writing. Generally speaking, read and write separation can be achieved using master-slave replication technology.
- Split table and split database
When the amount of data in the database is large, the split table and split database technology can be used to split the data into multiple tables or multiple databases to improve query efficiency and scalability. Table and database sharding need to be used with technologies such as vertical splitting and read-write separation.
In summary, PHP programming based on microservice architecture needs to focus on database optimization practices. Through technical means such as vertical splitting, index optimization, caching technology, read-write separation, and table and database partitioning, system performance and scalability can be improved, and data integrity and consistency can be ensured.

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
