laravel db migrate

// roll back
php artisan migrate:rollback
php artisan migrate:rollback --step=5  // rollback the last five migrations
php artisan migrate:reset  // roll back all of your application's migrations

roll back all of your migrations and then execute the  migrate command. This command effectively re-creates your entire database:
php artisan migrate:refresh
php artisan migrate:refresh --step=5

//drop all tables and re-run all migrations
php artisan migrate:fresh
