Where Does Symfony Store Cache and Env Config?
Symfony keeps env config in .env files at project root with cache in var/cache, logs in var/log, and sessions beside them per environment.
Last updated
Symfony organizes per project state in var/ with cache, log, and sessions subfolders per environment. Configuration flows from .env files at root through environment specific overrides. The framework compiles containers into cache for speed.
Cache staleness causes the classic updated code, old behavior confusion. Clearing the environment folder forces full rebuilds. Logs beside the cache capture runtime issues per environment without mixing.
Where Symfony stores this, by platform
var/cache + .env
Per environment cache, logs, and sessions together. Env files at root configure connections. Clear cache folders to fix stale behavior.
var/cache + .env
Same project relative layout on Mac installs. Local env overrides stay gitignored. Cache rebuilds on demand.
var\cache + .env
Windows projects mirror the identical structure. WSL paths work transparently. Secrets stay out of committed files.
Frequently asked questions
How do I clear the Symfony cache?
Delete var/cache dev or prod folders to force rebuilds when config changes misbehave. Container compilation caches aggressively in prod. The cache warmer rebuilds on next request.
Where do Symfony secrets go?
Copy .env to .env.local with real credentials since .env commits with dummy values. The local file overrides per environment and stays gitignored. Never commit secrets into versioned env files.
