first thing is you need to write correct php syntax. <?php ?> like this.. bt <? ?> is ok..
bt it will give u unexpected errors.

the result you are echoing in the while loop should be like this

<tr>
<td><?php echo $rows['name']; ?></td>
<td><?php echo $rows['lastname']; ?></td>
<td><?php echo $rows['email']; ?></td>
// link to update.php and send value of id
<td align="center"><a href="update.php?id=<?php echo $rows['id']; ?>">update</a></td>
</tr>
