Takes advantage of the SPL. Much easier and maintainable than the previous revisions. Haven't done any benchmarks yet but I imagine it is much faster. "If you want to omit directories, remove the RecursiveIteratorIterator::SELF_FIRST part."
  1. <?php
  2. $path = realpath('/etc');
  3.  
  4. $objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
  5. foreach($objects as $name => $object){
  6.     echo "$name
";
  7. }
  8. ?>
