Overview of using php-fpm connection pool to improve database access performance: In web development, database access is one of the most frequent and time-consuming operations. The traditional method is to create a new database connection for each database operation and then close the connection after use. This method will cause frequent establishment and closing of database connections, increasing system overhead. In order to solve this problem, you can use php-fpm connection pool technology to improve database access performance. Principle of connection pool: Connection pool is a caching technology that combines a certain number of databases
