Thank you to both Yang and Peter; the problem is, as you suggested, in the line: while ($filename = (readdir($dh) !== false)) and it now works correctly. I knew I was having a case of the stupids but couldn't find it. Also, thank you Jeffery. I was aware of scandir() and this was sort of a random choice but when it didn't work it refocused my mind onto the question of "why not" instead of a workaround. Surprising how easily we can fall down the wrong rabbit hole! Thanks again fellows for the prompt replies.
