[PHP] fwrite and sort

[Sebastian]

i have a form with checkboxes which after POST it writes to a file.
i would like to allow the user to sort the selected checkbox filename in the
order they want it written to file.

so i was thinking creating an input text box where they can enter a number,
then have it written to file in that order.. question is how?
the script starts like such:

  foreach($_POST['map'] AS $file)
  {
   if(file_exists('/maps/'.trim($file)))
   {
$found .= $file;
   }
  }

  if (file_exists($mapcycle) && $found)
  {
   $fp = fopen($mapcycle, 'w');
   fwrite($fp, $found);
   fclose($fp);
  }

any help is appreciated.
