Use Cache::memo() to combine persistent cache stores with per-request memory caching, preventing repetitive network roundtrips during a single HTTP request.
Calling `Cache::get('key')` multiple times in a single request still incurs a Redis network roundtrip or database query each time.
`Cache::memo()` wraps your configured cache store with an in-memory array cache for the duration of the current request:
use Illuminate\Support\Facades\Cache;
// Standard Cache: 3 Redis network roundtrips
$permissions = Cache::get('user.permissions'); // Redis query
$permissions = Cache::get('user.permissions'); // Redis query
$permissions = Cache::get('user.permissions'); // Redis query
// Cache::memo(): 1 Redis query, subsequent calls read from memory
$permissions = Cache::memo()->get('user.permissions'); // Redis query
$permissions = Cache::memo()->get('user.permissions'); // In-memory hit
$permissions = Cache::memo()->get('user.permissions'); // In-memory hit
// Mutations automatically sync the persistent store and invalidate local memory
Cache::memo()->put('user.status', 'active');
Cache::memo()->increment('page.views');
// Works with specific cache stores
Cache::memo('redis')->remember('expensive-report', 3600, fn () =>
$this->buildReport()
);- Eliminates redundant cache store queries during heavy request lifecycles
- In-memory values reset automatically at the end of the HTTP request
- Mutation methods (
put,increment,forget) keep memory and storage in sync
