PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

Go language error handling becomes more flexible and readable through errors.Is and errors.As functions. 1.errors.Is is used to check whether the error is the same as the specified error and is suitable for the processing of the error chain. 2.errors.As can not only check the error type, but also convert the error to a specific type, which is convenient for extracting error information. Using these functions can simplify error handling logic, but pay attention to the correct delivery of error chains and avoid excessive dependence to prevent code complexity.
