  21. 21. www.techtic.com | info@techtic.com ->save() method can accept parameters? As a result, we can tell it to “ignore” updated_at default functionality to be filled with current timestamp. See this: 17 Override updated_at when saving Overriding default updated_at with our pre-defined one. Laravel Tips
  22. 22. www.techtic.com | info@techtic.com This code actually returns? 18 What is the result of an update()? what would that $result contain? The answer is affected rows.
