here's a gotcha! If you are using
while ($file = readdir($dh))
{
echo "$file\n";
}
and your script comes across a directory called ./0 (i.e. zero),
the expression will evaluate to false, and the loop will end unexpectedly.
What you need to do is the following:
while (($file = readdir($dh)) !== false)
{
echo "$file\n";
}
closedir($dh);
