Config.php Access

In PHP web development, a config.php file is a custom script used to store sensitive site-wide settings—most notably database credentials—so they can be easily managed in one place and included in other scripts. Core Purpose and Contents

• Consider using environment variables to store sensitive information instead of hardcoding it in config.php.

• Use environment variables for secrets and sensitive settings; load them with a library (e.g., vlucas/phpdotenv) into config at runtime.
• For containerized apps, inject environment variables through container orchestration (Docker/Kubernetes secrets).
• Use secret management services (AWS Secrets Manager, HashiCorp Vault) in production for dynamic rotation and auditing.
