<div id="f2"> <h3>files available download</h3> <p> <?php // list contents of user directory if (file_exists($user_directory)) {     if ($handle = opendir($user_directory)) {         while (false !== ($entry = readdir($handle))) {             if ($entry != "." && $entry != "..") {                 echo "<a href='download_file.php?filename=".urlencode($entry)."'>".$entry."</a><br/>";             }         }     closedir($handle);     } }  ?> </p>  </div>

pulled link http://codebyte.dev7studios.com/post/1590919646/php-format-filesize, should ever cease exist:

function filesize_format($size, $sizes = array('bytes', 'kb', 'mb', 'gb', 'tb', 'pb', 'eb', 'zb', 'yb')) {     if ($size == 0) return('n/a');     return (round($size/pow(1024, ($i = floor(log($size, 1024)))), 2) . ' ' . $sizes[$i]); }
