i list files , folders using recursivedirectoryiterator, , display result same way explorer do. need indent subfolders, have no idea how that... use subfolder counter, work level 1, level 2 wouldn't work...
here's code :
$nb=1; $read_folder = './cases/'; $iterator = new recursiveiteratoriterator(new recursivedirectoryiterator($read_folder), recursiveiteratoriterator::self_first); foreach ($iterator $file) { $nb++; if ($file->isdir()) { $list_docs .= '<li class="docresult"><i class="fa fa-folder"></i> <span id="file_'.$nb.'">'.$file->getfilename().'</span></li>'; } else { $list_docs .= '<li class="docresult"><i class="fa fa-file-o"></i> <span id="file_'.$nb.'">'.$file->getfilename().'</span></li>'; } }
this version 2 of program traverse directory tree.
it has different program because of requirement sort output directories , printed before files.
now, seemed simple when started searching answers. hmm... ;-/
i came conclusion either have use ready made package such synfony : finder component or write own directory iterator component.
i have done latter , made own sorteddirectory class.
the output not formatted in way. uses default styling of browser.
the source code class sorteddirectory available.
the code:

"counts: dir: $dircount, files: $filecount" .'</li>'; return $list_docs .= '</ul>'; } the sorteddirectory class:
if want change sort order edit:
private function cmpentry(splfileinfo $entry1, splfileinfo $entry2)
