Laravel - Getting Started - Updates

The save method may also be used to update models that already exist in the database. To update a model, you should retrieve it and set any attributes you wish to update. Then, you should call the model's save method. Again, the updated_at timestamp will automatically be updated, so there is no need to manually set its value:

    use App\Models\Flight;
    $flight = Flight::find(1);
    $flight->name = 'Paris to London';
