Filtering output

[smordue]

I am using the following code, which you guys helped me with last week.

 

<?php
$cur_group = '';
$files = scandir('images/siteimgs');
sort($files);
$thelist .= '<option selected="selected"';
$thelist .= '>Select Site Image</option>';
foreach($files as $file) {
if ($file == '.' || $file == '..') { continue; }
   $file_x = substr($file, 0, -4);
   $file_y = explode("-", $file_x);
   $group = substr($file, 0, strpos($file, '-'));
   if(empty($cur_group)) {
      $thelist .= '<optgroup label="'.$group.'">';
      $cur_group = $group;
   }
   if($group != $cur_group) {
      $thelist .= '</optgroup>';
      $thelist .= '<optgroup label="'.$group.'">';
      $cur_group = $group;
   }
   $thelist .= '<option value="picture-switcher.php?picture='.$file_x.'">'.$file_y[1].'</option>';
}
?><select onchange="window.location.href=this.options[this.selectedIndex].value">
<?php echo $thelist; ?>
</select>

 

It is working great, but I have a new need and that is to on another page, filter the results to only show images with a certain prefix.

 

My images are like so:

 

Finance-Money.jpg

Legal-Gavel.jpg

 

etc.

 

I would like to add something to the above code so that it only shows the images that start with "Legal-" for example.

 

Thanks for your help, I could not do this without you guys!
