mtime problem with gallery script

reverse mtime

[Champak]

Please help with the following code. The creator no longer supports it, I don't want to change scripts, and I'm trying to do something simple to it. It is set up to order the pictures by the date they were modified----"mtime", I would like to reverse the mtime so it is ordered latest to oldest, instead of oldest to latest. Any help please. I have edited out a good portion of this script that I THINK is not needed in order to figure this out because of its size and being unable to post, if the rest is needed please let me know.

<snipped code, see next post>

It all happens when the directory is read. You just need to modify that function, maybe pass a sort sequence to it and set a default so that you won't have to modify any of the existing processes except where you are calling the function and you want it loaded in a different sort order. I see that the original code even has a sort command commented out. Note the bold changes and click the linked functions for more information:

function [php.net] load_dir($sortBy = 'name', $sortOrder = 'ASC') 
{ 
 global $dirs;  
 global $imgs;  
 global $pref; 
 $lastmod = 0;  
 $dh = opendir('.');  
 while (($file = readdir($dh)) !== false) {  
  if (is_dir($file)) {  
   $dirs[] = $file;  
  } else if (is_readable($file)) {  
   $ext = getValidExtension($file);  
   if($ext) {  
    $when = filemtime($file);  
    $imgs[$file] = $when;  
    if ($when > $lastmod) {  
     $lastmod = $when;  
    }  
   //} # end if ft  
  }# end elseif  
 } #end while  
closedir($dh); 
if ($sortBy == 'name') { 
 ksort [php.net]($imgs); 
} else { 
 asort [php.net]($imgs); 
} 
if ($sortOrder == 'DESC') { 
 $imgs = array_reverse [php.net]($imgs, true); 
} 
//print "Sort By: $sortBy\nSort Order: $sortOrder\n"; 
//print '<pre>'; print_r($imgs); print '</pre>'; 
return $lastmod;  
#sort($imgs);  
} #end load_dir

Test run the code:

// A default listing (name, ascending): 
load_dir(); 
//load_dir('name', 'ASC'); // <- Same as above 
// Sort by name, descending 
load_dir('name', 'DESC'); 
// Sort by time, ascending 
load_dir('time'); 
//load_dir('time', 'ASC'); // <- Same as above 
// Sort by time, descending 
load_dir('time', 'DESC');
