Redo this Statement for Newest to Latest?

Hey there fellow DP'ers!

I got a PHP code that opendir's a directory and in alphabetical order displays the contents of the folder (images) in pages. I wish to convert this so instead of alphabetical it will be newest to last.

if ($handle = opendir('defaultimages')) {
   while (false !== ($file = readdir($handle))) {
       if ($file != "." && $file != "css" && $file != "..") {
           $files[] = $file;
       }
   }
   closedir($handle);
}

$array_lowercase = array_map('strtolower', $files);
array_multisort($array_lowercase, SORT_ASC, SORT_STRING, $files);

$count=0; $path = 'defaultimages/';
$perpage = '12';
$numpages = count($files) / $perpage;
$page=$_REQUEST['page'];if(!$page){$page=1;}

$start = $perpage * $page - $perpage;
$end = $perpage * page;

if($perpage*$page > count($files)){ $last=count($files); }else{ $last=$perpage*$page; }

PHP:

How would I go about doing that? if that is my current statement.

Cheers!

 

What you do is create a 'key' to sort on with the data you need - file read time, and lowercase filename:

$dir='defaultimages';
$files=array();
if ($handle = opendir($dir)) 
{
  while (false !== ($file = readdir($handle))) 
  {
    if ($file != "." && $file != "css" && $file != "..") 
    {
      $date=filemtime($file);
      // create unique keyfield we can sort on - time first, unique filename after
      $keyField=$date.'-'.strtolower($file);
      $files[$keyField]=array('file'=>$file,'date'=>$date);
    }
  }
  closedir($handle);
}
krsort($files);
// output
echo '<pre>';
foreach ($files as $file)
{
  $date=date('r',$file['date']);
  echo "Date: ",$date," Filename: ",$file['file'],"<br />";
}
echo '</pre>';

PHP:

'krsort' sorts on the key in reverse order (so highest/newest dates come first), and the bottom part shows the results.

The 'key' to it is preparing the array when reading in - using a custom key for each entry makes sorting easy after, and much easier to change.
