How do I use page caching in PHP?
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.

Best way to organize helper functions in a PHP project?
Article Introduction：There are four practical methods for organizing helper functions in PHP projects: 1. Use a single or multiple helper files, suitable for small projects, placed in the core directory and loaded as soon as possible; 2. Group helper functions into static classes by category to improve readability and maintainability; 3. Automatically load global auxiliary files through Composer's autoload to ensure convenient access; 4. Use namespace and folder structure to manage a large number of auxiliary classes, such as class files divided by functions under App\Helpers. These methods are selected according to the project size. Small projects can use a single file, while large projects are suitable for using structured classes under namespace.
