laravel:constants-and-configuration

To refactor hardcoded values in Laravel, replace magic numbers and strings with PHP constants, enums, and configuration files. This improves maintainability and debuggability by using descriptive references like config keys or enum cases instead of raw values.

The best way to manage environment-specific configuration is using Laravel's configuration system. It centralizes application-wide and feature-specific settings, allowing you to define values in config files that can adapt based on the current environment.

Yes, this refactoring approach supports PHP 8.1+ enums. You can use enums to define fixed values and states, replacing hardcoded strings to improve code readability and type safety throughout your application.

You need database-driven settings when configuration values must be managed dynamically at runtime. Implementing a Settings model allows you to change configuration on the fly without requiring code deployment or modifying configuration files.

To ensure consistency across Laravel services, define cache keys and validation rules as constants within the services themselves. This replaces scattered hardcoded values with centralized, reusable service-specific constants.

A limitation of replacing hardcoded values with constants and enums is reduced flexibility for values that change frequently. Enums and constants are immutable, so values needing runtime modification should use database-driven settings instead.
