Usort Feeds By Relevance

P: 59
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

/************************************************** ******************

Nothing too exciting here. Just a sample page that demos integrated
Multifeeds support as well as cached favicons and perhaps a few other

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 internationalized domain names.

// Initialize some feeds for use.
$feed = new SimplePie();

// When we set these, we need to make sure that the handler_image.php file is also trying to read from the same cache directory that we are.

// Initialize the feed.

// Make sure the page is being served with the UTF-8 headers.

// Begin the (X)HTML page.

<div id="site">

<?php if ($feed->error): ?>
<?php endif ?>

<div class="chunk">
<h1>Quick-n-Dirty Multifeeds Demo</a></h1>

// Let's loop through each item in the feed.
foreach($feed->get_items() as $item):

// Let's give ourselves a reference to the parent $feed object for this particular item.
$feed = $item->get_feed();

<div class="chunk">
<h4 style="background-image:url(<?php echo $feed->get_favicon(); ?>);"><a href="<?php echo $item->get_permalink(); ?>"><?php echo html_entity_decode($item->get_title(), ENT_QUOTES, 'UTF-8'); ?></a></h4>

<!-- get_content() prefers full content over summaries -->
<?php echo $item->get_content(); ?>

<?php if ($enclosure = $item->get_enclosure()): ?>
<?php echo $enclosure->native_embed(array(
// New 'mediaplayer' attribute shows off Flash-based MP3 and FLV playback.
'mediaplayer' => '../demo/for_the_demo/mediaplayer.swf'
)); ?>
<?php endif; ?>

<p class="footnote">Source: <a href="<?php echo $feed->get_permalink(); ?>"><?php echo $feed->get_title(); ?></a> | <?php echo $item->get_date('j M Y | g:i a'); ?></p>

<?php endforeach ?>

<p class="footnote">This is a test of the emergency broadcast system. This is only a test&hellip; beeeeeeeeeeeeeeeeeeeeeeeeeep!</p>

This is the sort of usort i will use


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(),$term))
$x = 2;
elseif (stripos($a->get_content(),$term))
$x = 1;

$y = 0;
if (stripos($b->get_title(),$term))
$y = 2;
elseif (stripos($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?

Do not start a second thread when the first one does not run!
