About the functions of eloquent fillable and guard properties in Laravel

Recently learning Laravel, with the version of 4.2, in the study of eloquent and then wrote an example to see two properties, Google a bit or not how to understand that you want to ask the following code

...    protected $guard = array('email','password');    protected $fillable = array('nickname','email','password');    protected $hidden = array('password', 'remember_token');...

What is the role of each of the three properties?

The first two are blacklisted and whitelisted for AutoFill Mass assignment. A third party hides the attribute when converting an array or JSON.
