Hi guys, can someone help me please with a beginners PHP problem.
I want to create a widget for my CMS using the following code to list files as links. I'm fine with the basics of creating a widget, but I need a little help please to implement this code.

<?php
$count = 0;
if ($handle = opendir('./mp3')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {$count++;
print("<a href=\"".$file."\">".$file."</a><br />\n");
}
}
echo '<br /><br /><a href="..">Return</a>';
closedir($handle);
}
?>

The above code will display files as links in a given folder, I just need to make it work as a widget.
Thanks for your time.
