Change your while condition in Method load()
from
while ($directory = $directory->read())
to
while ($item= $directory->read())

In the conclusion of the article relating to Possible enhancements, it states that "One of the main ones being that the HTML code is echoed out, which makes working with it kind of confusing". I am not certain I understand the problem and what alternative(s) would you suggest.

Hi Garry, it means that it doesn't use any HTML template but uses the echo() function to render HTML code instead. Ideally, HTML code and PHP code should be separated.

Thanks David for your clarification although now you have caused me to study the concept/use of HTML templates as I have been using the 'echo' function. Any suggestions where I could begin my further reading and study? Thanks again for your assistance.
