Reference One Variable to Another in .env File in Laravel

In Laravel projects, configuration settings are usually defined in the .env file. Many times, you may want to reference one variable to another within this file. In such cases, Laravel allows you to use the ${} string pattern. This way, you can call a variable you have previously defined within another variable.

How To?

You can use the following method to reference one variable to another in the

.env file:

APP_NAME=Netsper
DASHBOARD_TITLE="${APP_NAME} Dashboard"

With this configuration, the DASHBOARD_TITLE variable will now have the value "Netsper Dashboard". You have created a new string by directly using the first variable, APP_NAME.

You can easily use this simple but effective method in your projects!
