Environment variables

It is often helpful to have different configuration values based on the environment where the application is running.

For example, you may wish to use a different cache driver locally than you do on your production server.

Kiaan's default resources\settings.env file contains some common configuration values that may differ based on whether your application is running locally or on a production web server. These values are then retrieved from various Kiaan configuration files within the config directory using Kiaan's env function.

Define a variable

To define a variable, it must be defined on a single line

Comments

You can define the line as a comment if preceded by "#"
