Laravel 5.1.11 migrate with php artisan does not work for me

I am new to Laravel. I am using Laravel 5.1.11 but when I try to run php artisan migrate command I am faced with the following error message:

[symfony\Component\Debug\Exception\FatalErrorException] syntax Error, unexpected 'public' (T_PUBLIC)

I have searched google for support but unfortunately could not find matching answers for me.

With database connection configuration in database.php and .env is quite fine coz php artisan migrate:install works just fine.

Please any help.
