PHP inserting variable into a link href and name

This is the code I am working with:

<?php
    $rss = new DOMDocument();
    $rss->load('http://hugeriver.wordpress.com/feed/');
    $feed = array();
    foreach ($rss->getElementsByTagName('item') as $node) {
        $item = array ( 
            'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
            'desc' => $node->getElementsByTagName('encoded')->item(0)->nodeValue,
            'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
            'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
            );
        array_push($feed, $item);
    }
    $limit = count($feed);
    for($x=0;$x<$limit;$x++) {
        $title = str_replace(' & ', ' &amp; ', $feed[$x]['title']);
        $link = $feed[$x]['link'];
        $description = $feed[$x]['desc'];
        $date = date('l F d, Y', strtotime($feed[$x]['date']));
        echo '<h2><a name="test">'.$title.'</a><span class="line"></span></h2>';
        echo '<small><em>Posted on '.$date.'</em></small></p>';
        echo '<p>'.$description.'</p>';
    }
?>

I am stuck specifically with this line. I am trying to make it so the title is both the name of the ancor and the link (so when clicked it scrolls to the top). This is what I tried that doesn't work. Can anyone please show me what is wrong with my syntax?

echo '<h2><a name="'.$title'" href="#'.$title'">'.$title.'</a><span class="line"></span></h2>';
