body: <p><img src="https://i.stack.imgur.com/tOQwD.png" alt="delAction"></p>
  
  <p>I am searching for a long time on net, but no luck. Please help or try to give some ideas how to achieve this.</p>
  
  <p>I want to delete some data like:</p>
  
  <pre><code>$articleIds = '1,2,3,5,8';
  $User    = new User();
  $success = $User-&gt;delete($articleIds);  
  </code></pre>
  
  <p>But, that gives an error. What should I do?</p>
  
  <p>Thanks in advance.</p>
