What is Laravel advanced configuration caching strategy?
Updated May 16, 2026
Short answer
Configuration caching compiles all config files into a single cached file for faster loading.
Deep explanation
Laravel loads configuration files on every request unless cached. config:cache command compiles all config into a single optimized file. This reduces filesystem reads and improves performance significantly in production. However, dynamic env changes require cache refresh.
Real-world example
Used in production deployments for faster boot time.
Common mistakes
- Changing .env without clearing config cache.
