Attention

7. Add custom environment variables¶
If your application requires a variable to determine if it is run under development or production, you can easily add it and make PHP aware of it.

7.1. Add custom environment variables¶
This is fairly simple. Any variable inside the .env
file is considered an environment variable
and automatically known to PHP.
If you for example require a variable APPLICATION_ENV
, with a value of production
, you
would add the following to the .env
file:
APPLICATION_ENV=production
You need to restart the Devilbox for the changes to take effect.
Note
There is already a proposed section inside the .env
file at the very bottom
to add you custom variables to differentiate them from the Devilbox required variables.
7.2. Use custom environment variables¶
Accessing the above defined environment variable on the PHP side is also fairly simple.
You can use the PHP’s built-in function getenv
to obtain the value:
<?php
// Example use of getenv()
echo getenv('APPLICATION_ENV');
?>
