order into which files are read for $dir

[Sarah]

I am reading a directory using $dir and putting the values into an array - now the order into which the details go into the array are wrong - I want it alphabetically - how is it best to do this?

As I am paging through I cannot do a sort afterwards as that screws up all the other pages?

Is there a way that I can re-order the array after its read the directory using correct values etc?

My code (snipped) is below

Any help on this would be great as its bugging me

Thanks
Sarah

//dv(DIR_FS_CATALOG . 'images/' . $products_photo_dir);

    $dir = dir(DIR_FS_CATALOG . '/images/' . $products_photo_dir . '/');  

//    $dir_info[] = array('id' => '', 'text' => "Main Directory");

    while ($file = $dir->read()) {  

      if (is_file(DIR_FS_CATALOG . '/images/' . $products_photo_dir . '/' . $file))    {// && strtoupper($file) != 'CVS' && $file != "." && $file != "..") {

//dv($file);

//        $dir_info[] = array('id' => $file . '/', 'text' => $file);

           if(preg_match('/.*\.jpg$/', $file, $matches))    { 

           if(strpos($file, '_LRG'))    continue;

           $files[] = $file;

//             echo '<img src="/images/'.$products_photo_dir.'/'.$file.'" align="bottom" />'."<br />\n";

//           echo $file."<br /><br />\n";

        }

      }

    } 

# COULD I DO A RESORT ON ARRAY HERE INSTEAD? HOW BEST TO DO THIS?

#echo "<pre>".print_r($files)."</pre>";

#    natsort($files);  <- IF I SORT HERE IT SCREWS UP PAGINATION LATER ON

# sort above went strange look at sort(), arsort(), asort(), ksort(), 

# natsort(), natcasesort(), rsort(), usort(), array_multisort(), and uksort() on php site

#echo "<pre>".print_r($files)."</pre>";

    $num_files = sizeof($files);

    $this_col = 1;   

       echo "<tr>\n";

       if($_GET['start'] != '' && $_GET['start'] != '0')    {

           $start    = (int)$_GET['start'];

        $stop     = $start; 

        for($i=0;$i<$stop;$i++)    {

            unset($files[$i]);

        }

       }    //else    $start = PHOTOS_NUMBER_PER_PAGE; 

printing the array to the page gives this (again snipped):
