Why Isn't My Laravel 5.2 Application Reading My .env File Changes?

Laravel Unable to Read .env File Changes

After upgrading to Laravel 5.2, users have encountered issues reading values from the .env file, affecting configuration in various files. The config/database.php file, for instance, attempts to retrieve database values from .env, but encounters errors indicating authentication failures with forge credentials.

One potential cause of this issue is whitespace within .env variables. If any variable contains spaces, it must be wrapped in double-quotes. For example, instead of:

SITE_NAME=My website

Use:

SITE_NAME="My website"

Additionally, Laravel 5.2 introduced changes to the env() helper function. It now requires the second parameter to be a non-null default value, which can lead to issues when values in .env are not set. To resolve this, make sure that the second parameter of env() is set to a default value that makes sense for your application.

Furthermore, it's essential to clear the Laravel cache after making these modifications. Run the following commands to refresh the cache and apply the changes:

php artisan config:cache
php artisan config:clear

By following these steps, you should be able to resolve the issue where Laravel fails to read changes to the .env file.
