RecursiveIteratorIterator and RecursiveDirectoryIterator to nested html lists

Question

Here\'s my php script:

Answer 1

Here is one using DomDocument

The basic idea is the contents of each directory is represented by a

and each element in the directory by a
• 
  If element is a non-empty directory it will contain a
  to represent its contens and so on.

  $path = $_SERVER['DOCUMENT_ROOT'].'/test';
  $objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
  $dom = new DomDocument("1.0");
  $list = $dom->createElement("ul");
  $dom->appendChild($list);
  $node = $list;
  $depth = 0;
  foreach($objects as $name => $object){  
      if ($objects->getDepth() == $depth){
  //the depth hasnt changed so just add another li
          $li = $dom->createElement('li', $object->getFilename());
          $node->appendChild($li);
      }
      elseif ($objects->getDepth() > $depth){
  //the depth increased, the last li is a non-empty folder 
          $li = $node->lastChild;
          $ul = $dom->createElement('ul');
          $li->appendChild($ul);
          $ul->appendChild($dom->createElement('li', $object->getFilename()));
          $node = $ul;
      }
      else{
  //the depth decreased, going up $difference directories
          $difference = $depth - $objects->getDepth();
          for ($i = 0; $i < $difference; $difference--){
              $node = $node->parentNode->parentNode;
          }
          $li = $dom->createElement('li', $object->getFilename());
          $node->appendChild($li);
      }
      $depth = $objects->getDepth();
  }
  echo $dom->saveHtml();
  

  The out put will be along the lines of

  
      
  dir1
      
  dir2
          
  
              
  in dir2
          
  
      
  file in root
