Empty array on lang file throws offset error when syncing

[lacrc]

• Laravel Version: 5.7.12
• PHP Version: 7.2.9

Description:

By far not an urgent issue, just thought I should report that running php artisan langman:sync throws ErrorException : Undefined offset: 2 when "Synchronizing language files..." if you have any php lang file that only returns an empty array.

Steps to reproduce:

• Create a .php file in any of your lang folders;
• Edit it so it returns just an empty array:

<?php

return [
    //
];

• Run php artisan langman:sync

is there any fix about this?

what I did was create a dummy entry on every new file like:

<?php

return [
    '' => ''
];

Sync ran successfully after that.
