sorting directory list in dropdown

[Shamrox]

Alright, I've got this drop down working where it pulls all the files in. Is there a way to sort them alphabetically?
Here's the code. Thanks for the assist.

[code]
><select name='filename' id='filename'>
<?php
if ($handle = opendir('/path/to/the/options_sheets')) {
  /* This is the correct way to loop over the directory. */
  while (false !== ($file = readdir($handle))) {
  if ($file != "." && $file != "..") {
      echo "<option value='$file\n'>$file\n</option>";
  }
  }
  closedir($handle);
}
?>
</select>
[/code]

You could load all the file names into an array, then sort the array....

just to let you know,
$files[] = $filename
this has to be used within a loop...(above)
and there are a lot of different sorts, the basic ones are
sort()
sorts alphebitcally
and
rsort()
oppisite sort()
but these two are case sensitive, for none case sensitive sorts, natcasort() would be a better choice...
