title: How does Routing work in PHP laravel?
body: <p>I have just started playing with <code>Laravel</code> framework and I have seen this : </p>
  
  <pre><code>  Route::get('foo', function () {
      return 'Hello World';
  });
  </code></pre>
  
  <p>Can some one please explain what is this ? I mean over all I know what is get . but why do we put 'foo' and then the closure we put ? 
  Also where am I really getting the information from ? </p>
