====== Mastodon RSS Bookmarks ======
Mastodon considers your bookmark list to be private information.  I'm happy to share mine.  Plus, I wanted a way to add any bookmarks I make there into a 'Read later' category in my RSS reader (which is also where my phone and browser bookmarks go).

This was pretty simple, I create a PHP file that gets the latest 20 bookmarks (default API endpoint ''/api/v1/bookmarks'') and takes an access token from your mastodon 'development' admin page.

Then I can give this URL to my RSS reader: https://neil.mckillop.org/stuff/mastodon_bookmarks.rss 

<code php get_mastodon_bookmarks.php>
<?php
header('Content-Type: text/xml');
$bearer = "get your access token from the development page in the mastodon web client settings";
$instance = "glasgow.social";
$headers = [
  'Authorization: Bearer '.$bearer,
];

$ch_bookmarks = curl_init();
curl_setopt($ch_bookmarks, CURLOPT_URL, "https://$instance/api/v1/bookmarks");
curl_setopt($ch_bookmarks, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch_bookmarks, CURLOPT_HTTPHEADER, $headers);

$bookmarks = json_decode(curl_exec($ch_bookmarks), true);

curl_close ($ch_bookmarks);

$xml_header = <<<EOT

foreach($bookmarks as $k=>$v) {
        $xml_item[$k] = "\n\t<item>
                <title>{$v['card']['title']}</title>
