Answer 1

You can write it in line. This link will be inserted into the page only if the user has admin status:
<ul>
<li>All users will see this link</li>
<?php
if ($row[3]=="admin") {
echo "<li><a href='adminStuff.php'>hidden link</a></a>";
}
?>
</ul>
I am pretty sure that is what you meant, or if you want to do conditional redirects, I think you already have that done.

Answer 2

Try this :
<?php if ($_SESSION['userType'] == 'admin'): ?>
<a>Only admin can see this. </a>
<?php else if($_SESSION['userType'] == 'user' ): ?>
<a>Only user can see this</a>
<?php endif ?>
