Echo an Array Key.. how? - php

Question

Im looking to echo the value of my array key out into the view for this controller. I cant quite figure it out. So for the first feed I want to echo mmafighting into the of the view. Then it would loop through the rest.
Here is my controller code:
function index()
{
$this->load->library('simplepie');
$feeds = array('mmafighting' => 'http://www.mmafighting.com/rss/current',
'bbc' => 'http://feeds.bbci.co.uk/news/world/us_and_canada/rss.xml',
'bloodyelbow' => 'http://www.bloodyelbow.com/rss',
'ufc' => 'http://www.ufc.com/rss/news',
'hackernews' => 'http://news.ycombinator.com/rss',
'msnbc' => 'http://www.msn.com/rss/news.aspx',
'msnbc2' => 'http://www.msn.com/rss/msnmoney.aspx',
'msnbc3' => 'http://www.msn.com/rss/msnshopping_top.aspx'
);
foreach ($feeds as $site=>$url)
{
$data['feed'][$site] = new SimplePie();
$data['feed'][$site]->set_feed_url($url);
$data['feed'][$site]->set_cache_location(APPPATH.'cache');
$data['feed'][$site]->set_cache_duration(300);
$data['feed'][$site]->init();
$data['feed'][$site]->handle_content_type();
}
$this->load->view('feedsview', $data);
}
Here is my view code:
<?php
$feedCount = 0;
$rowCount = 0;
?>
<?php foreach ($feed as $site): ?>
<?php if ($site->data): ?>
<div class="feed">
<h2><?php // echo original array key here ?></h2>
<ul>
<?php $items = $site->get_items(0, 5); ?>
<?php foreach ($items as $item): ?>
<li><?php echo $item->get_title(); ?></li>
<?php endforeach; ?>
</ul>
</div>
<?php endif; ?>
<?php $feedCount++; ?>
<?php if ($feedCount === 3) {
echo '<div style="clear:both;"> </div>';
$feedCount = 0;
$rowCount++;
if ($rowCount === 2) {
echo '<div style="width:1000px; margin-bottom:20px;height:100px; border:1px solid #252525; float:left;">images</div>';
}
} ?>
<?php endforeach; ?>

I'm not sure i understand but what about doing this :
<?php foreach ($feed as $key => $site): ?>
<?php if ($site->data): ?>
<div class="feed">
<h2><?php echo $key ?></h2>
<ul>
