<?php
$files_to_hide = array('file1.txt', 'file2.txt');
if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle)))
    {
        if (($file != ".") && ($file != "..") && !in_array($file, $files_to_hide))
        {
            $thelist .= '<LI><a href="'.$file.'">'.$file.'</a>';
        }
    }

    closedir($handle);
}
