title: Laravel eloquent find in array from sql
body: <p>I'm developing a site with Laravel 4.2. I have two tables: <strong>articles</strong> and <strong>tags</strong>.</p>
  
  <p>This is my <strong>tags</strong> table:</p>
  
  <pre><code>id | article_ids | xxxx
  2  | 2,41,23,6   | xxxx
  </code></pre>
  
  <p>I'm using Eloquent and I want to find an specific id in article_ids column. 
  How can I do this? </p>
