[PHP] help sorting readdir values

[dan radom]

First I must state that I didn't write the code, and I'm not much of a programmer of 
any kind.  I'm hoping someone can tell me how to sort the filenames and file sizes 
returned by readdir and filesize in the below code.  Thanks in advance.

<?

function list_dir($dir)
        {
                $handle=opendir($dir);
                echo "<ul>";
                while ($file = readdir($handle))
                {
                    if ($file != '.' && $file != '..'  && !ereg("\.php$", $file)) {
                print ("<tr>\n<td>\n");
                                print ("<li><a
href=\"".$GLOBALS["path"].$file."\">".$file."</a>");
                print ("</td>\n");
                                if (is_dir($file))
                                        {

                   print ("</tr>\n");
            }
                }
                echo "</ul>";
                closedir($handle);
        }

$directory = "screenshots";

$GLOBALS["path"] = "http://".$HTTP_HOST."/".$directory."/";;

echo "<table>\n";
list_dir(".");
