body: <pre><code>$account = Account::Find(1);
  </code></pre>
  
  <p>I use this code to get row in table which id is 1 when I return the value It become <code>{"id":1,"0":1,"username":"Jack","1":"Jack","email":"jack@email.com","2":"email":"jack@email.com" }</code> although I don't have attributes ("0","1","2")</p>
