working image display PHP code but i'm having trouble getting it to sort...

On one of my sites i have a folder of images and it uses this code to display them:

  <?PHP
function createGallery($pathToImages, $pathToThumbs)
{
  $output = "<table cellspacing=\"0\" cellpadding=\"0\" width=\"90%\">\n";
  $output .= "<tr>\n";
  $dir = opendir($pathToThumbs);
  $counter = 0;
  while (false !== ($fname = readdir($dir)))
  {
    if ($fname != '.' && $fname != '..') 
    {
      $output .= "<td valign=\"middle\" align=\"center\" class=\"pictures\">\n
	  				<a href=\"#\" onClick=\"viewImage('{$pathToImages}{$fname}')\">\n";
      $output .= "<img src=\"{$pathToThumbs}{$fname}\" border=\"0\" />\n";
      $output .= "</a>\n</td>\n";
      $counter += 1;
      if ($counter % 4 == 0) {$output .= "</tr>\n<tr>";}
    }
  }
  closedir($dir);
  $output .= "</tr>\n";
  $output .= "</table>\n";
  $output .= "</body>\n";
  $output .= "</html>\n";
  echo $output;
}
createGallery("pictures/","pictures/thumbs/");
?>

PHP:

the problem is it sorts the images completely randomly. Id like to have the images be sorted by name or date added. what is the code to do this?

thanks!

 

bumppppppp

 

Try this:

<?PHP
function createGallery($pathToImages, $pathToThumbs)
{
  $files = array();

  $output = "<table cellspacing=\"0\" cellpadding=\"0\" width=\"90%\">\n";
  $output .= "<tr>\n";
  $dir = opendir($pathToThumbs);
  $counter = 0;
  while (false !== ($fname = readdir($dir)))
  {
    if ($fname != '.' && $fname != '..')
    {
       $files[] = $fname;
    }
  }
  closedir($dir);
  
  
  sort($files);

  foreach ($files as $fname)
  {
      $output .= "<td valign=\"middle\" align=\"center\" class=\"pictures\">\n
              <a href=\"#\" onClick=\"viewImage('{$pathToImages}{$fname}')\">\n";
      $output .= "<img src=\"{$pathToThumbs}{$fname}\" border=\"0\" />\n";
      $output .= "</a>\n</td>\n";
      $counter += 1;
      if ($counter % 4 == 0) {$output .= "</tr>\n<tr>";}
  }

  $output .= "</tr>\n";
  $output .= "</table>\n";
  $output .= "</body>\n";
  $output .= "</html>\n";
  echo $output;
}
createGallery("pictures/","pictures/thumbs/");
?>
