From the php manual
if ($handle = opendir('audio/1960')) {
echo "Directory handle: $handle\n";
echo "Entries:\n";
/* This is the correct way to loop over the directory. */
while (false !== ($entry = readdir($handle))) {
echo "$entry\n";
echo "<br>";
}
closedir($handle);
}
Is there a way to list the entries according to the order they are listed
in the directory?
such as
60-001
60-002
60-003

And, for that, you could use scandir()
See http://ca3.php.net/manual/en/function.scandir.php

I can use it as is, just wasn't expecting the list to be shown that way.

A directory does not have such "order". The sorting has to be done
afterwards.
