title: Is it possible to echo out the column(s) that are updated when UPDATING the db?
body: <p>When I update a row in my db using these codes below:</p>
  
  <pre><code>if ($stmt=$conn-&gt;prepare("UPDATE db SET col1=?,col2=? WHERE id = ?")) {
    $stmt-&gt;bind_param("sss",$col1,$col2,$id);
    $stmt-&gt;execute();
  
    $stmt-&gt;close();
  }
  </code></pre>
  
  <p>Is it possible to know/ print out the column(s) that are being updated?</p>
  
  <p>I was thinking to use this function <code>isset()</code> but maybe there's a better way for this</p>
