I want to display a directory that contains only PDF's. I'd like the user to click on a given line and have the appropriate PDF displayed. I copied some code from this site and had to modify it. I put the "breaking return" tag so that each file would be displayed on a separate line. The following code works fine, but I need the file listings to be sorted alphabetically. I've tried the sort function for $thelist in several places, but I can't seem to get it to work. I appreciate your help.

{
if ($file != "." && $file != "..")

$thelist .= '<a href="'.$file.'">'.$file.'</a>'.'<br />';
}
}
closedir($handle);
}

I changed the code after reading another post here. This works fine:
