How do you manage configuration files and environment settings in Slim Framework?

Answer: In Slim Framework, configuration files and environment settings can be managed using a combination of PHP arrays, environment variables, and dependency injection. Typically, you can create a configuration file (e.g., `config.php`) that returns an array of settings. Use the `Dotenv` library to load environment variables from a `.env` file. These settings can then be injected into your application or middleware via a container, allowing you to easily switch between environments and manage sensitive information. For example:

“`php
$container[‘settings’] = function() {
return require ‘config.php’;
};

// Loading environment variables
$dotenv = DotenvDotenv::createImmutable(__DIR__);
$dotenv->load();
“`

Make sure to access configuration within your application using the container’s settings, ensuring a clean separation of concerns.
