From the docs on file: "...file() returns the file in an array. Each element
of the array corresponds to a line in the file, with the newline still
attached."

So you actually get the text plus a newline character which can be removed
with trim. Simply replace

if ($handle = opendir("$main[$i]"))

with

if ($handle = opendir( trim($main[$i]) ))

You don't need the quotes in opendir in this case.

Put on your seatbelt. I'm gonna try something new.
