title: How to get fillable variable as array in laravel 4.2
body: <p>When we create any Model class we create protected variable fillable</p>
  
  <p>I use this like </p>
  
  <pre><code>$model = new Demo;
  $model-&gt;fillable // but now working
  $model-&gt;fillable() // but now working.
  </code></pre>
  
  <p>Actually i want to loop over that variable </p>
  
  <p>But i don't want to create any extra variable and don't wanto to change variable </p>
  
  <p>type from protected to public.</p>
  
  <p>Thanks in Advance....</p>
