-NAME
-
- MagpieRSS - a simple RSS integration tool
-
-SYNOPSIS
-
- require_once(rss_fetch.inc);
- $url = $_GET['url'];
- $rss = fetch_rss( $url );
-
- echo "Channel Title: " . $rss->channel['title'] . "<p>";
- echo "<ul>";
- foreach ($rss->items as $item) {
- $href = $item['link'];
- $title = $item['title'];
- echo "<li><a href=$href>$title</a></li>";
- }
- echo "</ul>";
-
-DESCRIPTION
-
- MapieRSS is an XML-based RSS parser in PHP. It attempts to be "PHP-like",
- and simple to use.
-
- Some features include:
-
- * supports RSS 0.9 - 1.0, with limited RSS 2.0 support
- * supports namespaces, and modules, including mod_content and mod_event
- * open minded [1]
- * simple, functional interface, to object oriented backend parser
- * automatic caching of parsed RSS objects makes its easy to integrate
- * supports conditional GET with Last-Modified, and ETag
- * uses constants for easy override of default behaviour
- * heavily commented
-
-
-1. By open minded I mean Magpie will accept any tag it finds in good faith that
- it was supposed to be here. For strict validation, look elsewhere.

-
-
-SJM - alpha-grade changes based on the version of Snoopy released with MagpieRSS 0.7
-
-comments to steve@minutillo.com
-
-Two additions:
-
-1) If this is PHP 4.3 or greater, and 'openssl' is available,
- use the PHP built in SSL support for "https" instead of calling curl externally.
- Use of external curl can still be forced by setting $use_curl = true.
-
- ref: http://us2.php.net/fsockopen
-
-2) HTTP Digest Authentication. If you set a username and password, basic auth
- will be tried first. If that fails, and the server sends back an
- WWW-Authenticate: Digest header, the request will be retried with the appropriate
- digest response. Only qop=auth is supported, with MD5 as the algorithm.
- I realize that sending basic auth first, and then following up with a digest
- challenge-response kind of defeats the purpose in terms of security.
