Question

I’m using this to return images in the order they were added to the directory, however I want them to be ordered from newest to older. How can I do it? Thanks

<?
$handle = @opendir("images");

if(!empty($handle)) {
  while(false !== ($file = readdir($handle))) {
    if(is_file("images/" . $file))
      echo '<img src="images/' . $file . '"><br><br>';
  }
}

closedir($handle);
?>

If you want them ordered from newest to older, then you cannot rely on just readdir. That order might be arbitrary. You’ll need to sort them by timestamps:

$files = glob("images/*");    // or opendir+readdir loop

$files = array_combine($files, array_map("filemtime", $files));
arsort($files);               // sorts by time

$files = array_keys($files);  // just leave filenames
