Hi
I Am using Simplepie to display some rss feeds, currently it displays them in date and time order but i want it to display them in relevance order by using a usort function.
here is the code for the page
[PHP]<?php
/*************** *************** *************** *************** ********
MULTIFEEDS TEST PAGE
Nothing too exciting here. Just a sample page that demos integrated
Multifeeds support as well as cached favicons and perhaps a few other
things.
Lots of this code is commented to help explain some of the new stuff.
Code was tested in PHP 5.2.2, but *should* also work with earlier
versions of PHP, as supported by SimplePie (PHP 4.1).
*************** *************** *************** *************** ********/
// Include the SimplePie library, and the one that handles internationaliz ed domain names.
require_once('. ./simplepie.inc') ;
require_once('. ./idn/idna_convert.cl ass.php');
// Initialize some feeds for use.
$feed = new SimplePie();
$feed->set_feed_url(a rray(
'http://rss.news.yahoo. com/rss/topstories',
'http://news.google.com/?output=atom',
'http://rss.cnn.com/rss/cnn_topstories. rss'
));
// When we set these, we need to make sure that the handler_image.p hp file is also trying to read from the same cache directory that we are.
$feed->set_favicon_ha ndler('./handler_image.p hp');
$feed->set_image_hand ler('./handler_image.p hp');
// Initialize the feed.
$feed->init();
// Make sure the page is being served with the UTF-8 headers.
$feed->handle_content _type();
// Begin the (X)HTML page.

This is the sort of usort i will use
[PHP]usort($feed,'fu nnySort');
function funnySort($a,$b )
{
// assign numerical value so we can sort on
// whether "term" is in title or content or neither
$term = 'funny';
$x = 0;
if (stripos($a->get_title(),$t erm))
$x = 2;
elseif (stripos($a->get_content(), $term))
$x = 1;
$y = 0;
if (stripos($b->get_title(),$t erm))
$y = 2;
elseif (stripos($b->get_content(), $term))
$y = 1;
return $x <= $y
} [/PHP]
How can i make this work together so that it displays the most relevant posts first?
Thanks
