Laravel request parameter encapsulation?

Some mvc frameworks under java and .net platforms have the following features:

Form data:

<code>user.name:'admin',
user.pwd:'123'</code>

mvc framework interface method

<code class="java">public String add(User user){
    ...
}</code>

The mvc framework will encapsulate the parameters in the request into the user parameter of the add method. Are there any related features in laravel? How to achieve?
