Create an RSS Feed of Files in a Directory

I record some radio broadcasts for offline/on-demand listening. Coupled with an RSS feed, I can get these downloaded to my podcast player of choice. Below is an example of such a feed that I put together last night.


$files = glob("/path/to/directory/*");
$files = array_combine($files, array_map("filemtime", $files));


$files = array_keys($files);

echo '<?xml version="1.0" encoding="UTF-8"?>
<rss xmlns:itunes="" version="2.0">


    <title>Title of Your Feed</title>
    <description>Description of Your Feed</description>
    <link>A homepage for your feed</link>
    <itunes:image href="http://path/to/feed/icon.jpg"/>

foreach ( $files as $file) {
  // the filenames that I'm working with include the date in them
  // with a little slicing and dicing of the names, I can get what I need for the date variable
  // there are likely better ways of doing this, but this seemed the mostly reliable route to take in my case
  $date = preg_replace('/regex.of.junk/', '', $file);
  $date = preg_replace('/regex.of.more.junk/', '', $date);
  $date = date('D, j M Y H:i:s', strtotime($date));

  // remove the directory structure from the filename
  // again, there are likely better ways of doing this, but I was on a preg_replace roll
  $file = preg_replace('/.*Filename/', 'Filename', $file);

  echo "
      <title>Title " . $date . "</title>
      <guid>" . $file . "</guid>
      <pubDate>" . $date . "</pubDate>
      <enclosure url='http://download/link/path/" . $file . "' type='audio/mpeg'/>

  // let's stop after creating an RSS item for 10 files
  if (++$i == 9) break;

echo "
