From laravel version 5.3^ there is a function to call the app name
config('app.name');
You can change the default name ‘Laravel’ inside this file
config/app.php
'name' => 'Laravel',
And also inside .env file
APP_NAME=your_app_name
for latter to work, in config/app.php the line where you set the name should be written like this: 'name' => env('APP_NAME', 'fallback_app_name'),
