Solve: Laravel env() Variable Always Returns Null Value

Published on Jun 12, 2020

The problem mainly occurs at the time of moving our project one server to another server. I’m writing about some possible solutions.

Solution 1

Make sure you have .env file at the root directory of your Laravel project. If there is no .env file, the rename .env.example to .env.

Solution 2

Sometimes it occurs for cache. You can clear configuration cache using following commands:

php artisan config:clear
php artisan optimize
php artisan config:cache

Solution 3

If the above 2 solutions didn’t work, you run these additional commands.

These commands will clear cache, compiled views and routes cache:

php artisan cache:clear
php artisan view:clear
php artisan route:clear

These will clear the current compiled files, update the classes it needs and then write them back out so you don’t have to do it again:

php artisan clear-compiled
composer dump-autoload
php artisan optimize
That’s it. Thank you. ?
