Question

I cannot foreach loop my comment & reply system. I read many article and example but can't apply these in my case.
This is my comment system with reply, here every think is working well. But reply form work for only last/new comment. So i need to loop each comment. But can't do, please help me.
global $dbh;
$results = mysqli_query($dbh,"SELECT * FROM comments_lite WHERE qazi_id='$tutid' ORDER BY id DESC LIMIT 5") or die(mysqli_error($dbh));
echo'<div class="comments"><div id="updates"><div class="content"><comment>';
// Show only main comment
while($row = mysqli_fetch_array($results))
{ $id = $row['id'];
$qazi_id = $row['qazi_id'];
$username = $row['username'];
$description = $row['description'];
$parent_id = $row['parent_id'];
$date = $row['date'];
//echo comment
echo'<div class="comment">
<div class="cdomment_cheder">';
echo'<p>'.$username.' Says:</p>';
echo'<span>'.$date.'</span><br/>
<div class="avatarcnt">
<img alt="" src="uploadprofile/'.$u_imgurl.'"/>
</div></div></div>
<div class="cdomment_text">';
if ($description=="") {echo '';}
else echo''.htmlentities($description).'<br>';
echo '</div>';
//reply
echo'<div class="reply_box">Reply</div>';
//Reply form
echo'<div id="loader"></div><div class="reply_here" id="reply_here-'.$id.'" style="display:none;">
<form action="" method="post" id="repfrm" enctype="multipart/form-data">
<fieldset id="cmntfs">
<input type="hidden" name="username" tabindex="1" id="author" value="'.$username.'"/>
<textarea name="replycom" rows="2" tabindex="4" id="replycom" value=""></textarea>
