Caching: Speeding Up Your Laravel Application

Caching stores results of expensive operations so they can be reused.

  ## Cache example
  
  ```php
  $stats = Cache::remember('home_stats', 60, function () {
    return [
      'posts' => Post::count(),
      'users' => User::count(),
    ];
  });
  ```
  
  ## Cache flow
  
  ```mermaid
  flowchart LR
    A[Request] --> B{Cache Hit?}
    B -->|Yes| C[Return Cached]
    B -->|No| D[Query DB]
    D --> E[Store Cache]
    E --> C
  ```
  
  Caching is critical for scalable systems.
  
  In the next tutorial, we will write automated tests.
