How do i add pagination and drill down to sub level directores?  Here is the code having problems adding pagintion and drill down to sub level directories showing onl pdf or txt files.

 

  <?php
$path = "../pdf/user1/";
$ctr = 0;
$pdf_dir = @opendir($path);
while ( false !== ($pdf_file = readdir($pdf_dir)) )
{
   // add checks for other image file types here, if you like
   if ( preg_match("/(\.pdf|\.txt)$/", $pdf_file) )
   {
      $pdffiles[$ctr] = $pdf_file;
      $ctr++;
   }
}
closedir($pdf_dir);
foreach($pdffiles as $key=>$val)
{
   ?>
   fadeimages[<?=$key?>]=["<?=$path?><?=$val?>", "", ""]
   <?php
}
?>
