After upgrading Laravel from 5.6 to 6.0, Call to undefined str_random() function not working

php laravel laravel-helper laravel-6 laravel-upgrade

I have upgraded Laravel from 5.6 to 6.0. Previously, default helper functions were running fine on the controllers, but now it says "undefined." In my controller, I have used the following.

$filename = str_random(12);

I am getting the following error.

message: "Call to undefined function App\Http\Controllers\str_random()"

I have also used the function, and it's saying the same thing.random()

Can somebody please guide me on what to do?.

I have run commands like:

composer dump-autoload

But I get the same error.
