Here is the code developed so

You can try this.

function removeEmptySubfolders($path){

  if(substr($path,-1)!= DIRECTORY_SEPARATOR){
    $path .= DIRECTORY_SEPARATOR;
  }
  $d2 = array('.','..');
  $dirs = array_diff(glob($path.'*', GLOB_ONLYDIR),$d2);
  foreach($dirs as $d){
    removeEmptySubfolders($d);
  }

  if(count(array_diff(glob($path.'*'),$d2))===0){
    $checkEmpSubDir = explode(DIRECTORY_SEPARATOR,$path);
    for($i=count($checkEmpSubDir)-1;$i>0;$i--){
      $path = substr(str_replace($checkEmpSubDir[$i],"",$path),0,-1);

      if(($files = @scandir($path)) && count($files) <= 2){
        rmdir($path);
      }
    }
  }
}
