Ok so I have figured it out
<?php
$getUser = $db->prepare("SELECT * FROM users");
$getUser->execute();
$users = $getUsers->fetchAll();
<table>
<tr>
<th>Username</th>
<th>Password</th>
</tr>
<?php foreach ($users as $user) { ?>
<tr>
<td><?php echo $users['username'] ?></td>
<td><?php echo $users['password'] ?></td>
</tr>
<?php } ?>
</table>
It now echo’s every username and password inside the table. even if I add new ones in the database I just hit refresh and they are added.
Sorry for writing my question in a confusing way.
