[Wolves] Problem with code

Wed Feb 16 20:00:53 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>
