Using DirectoryIterator to List Files in PHP

During the days of PHP4, the most common way of showing the files in a directory was like so:

PLAIN TEXT
PHP:
  1. if ($handle = opendir('/home/fernando/temp')) {
  2.    while (false !== ($file = readdir($handle))) {
  3.        if ($file != "." && $file != "..") {
  4.            print "$file <br />";
  5.        }
  6.    }
  7.    closedir($handle);
  8. }
