How can HTML outside of php tags do this?

Oh that was my mistake. I thought everything had to be within <?php ?> tags and any html had to be echoed to the page. I see I still have a lot to learn :) Thanks for the explanation guys.

It's a common misconception that everything has to be displayed using
echo. PHP is an embedded language. When the PHP engine sees an opening
PHP tag it starts parsing the PHP, when it sees a closing tag, it just
outputs the HTML.

The closing brace of the while loop is after the table row. It tells the
PHP engine to go back to the top of the loop and to continue doing so
until the condition is no longer true.

If you study the code generated by Dreamweaver for a repeat region,
you'll see that it uses the same principle. The only difference is that
Dreamweaver uses a do... while loop, rather than a simple while loop.

In the section:

<?php while ($newArray = mysqli_fetch_array($res, MYSQLI_ASSOC)){?>
<tr>
<td><?php echo $newArray['fldFirstName']; ?></td>
<td><?php echo $newArray['fldLastName']; ?></td>
</tr>
<?php } ?>

PHP repeats everything between while { and } for as many records as are
retrieve by mysql_fetch_array. It doesn't matter that the HTML tags aren't
echoed by PHP, the PHP processor will still repeat everything inside the
while loop. In the end the whole page is a PHP page, so the whole page is
run through the PHP processor, not just the PHP tags, so its able to repeat
the HTML as many times as needed.
