Article Introduction：PHP page caching improves website performance by reducing server load and speeding up page loading. 1. Basic file cache avoids repeated generation of dynamic content by generating static HTML files and providing services during the validity period; 2. Enable OPcache to compile PHP scripts into bytecode and store them in memory, improving execution efficiency; 3. For dynamic pages with parameters, they should be cached separately according to URL parameters, and avoid cached user-specific content; 4. Lightweight cache libraries such as PHPFastCache can be used to simplify development and support multiple storage drivers. Combining these methods can effectively optimize the caching strategy of PHP projects.
