For the same size screen, the higher the resolution, the better the picture quality. Introduction to resolution 1. Since the points, lines and surfaces on the screen are all composed of pixels, the more pixels the monitor can display, the finer the picture, and the more information can be displayed in the same screen area. 2.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.
