[Wolves] Problem with code

Wed Feb 16 20:00:52 GMT 2005

Can someone interpret this code for me - on my old server it correctly 
displayed the newest image added to
a webcam directory, on my new server it is displaying the biggest file?
Anyone know why?

<head><meta http-equiv="refresh" content="5"></head> <pre>
<?php
$latest_num = 0;

if ($handle = opendir('.')) {
      while (false !== ($file = readdir($handle))) {
       if (preg_match("/^test(\d+)/", $file, $matches)) {
           if ($matches[1] > $latest_num) {
               $biggest     = $matches[1];
               $latest_file = $file;
           }
           // echo " $file\n";
       }
   }

   closedir($handle);
}

echo "Latest file: $latest_file\n";

echo "<img src='$latest_file'>";

?>
</pre>
