How to introduce white space in following?
<p>The following snippet of PHP code creates <code>$desc</code> alright, but I like it to introduce two (2) blank spaces between every <code>dpItemFeatureList</code> found as it goes through its iteration.</p>

<p>I can't seem to garner exactly what or where to add a snippet to do this?</p>

<pre><code>function get_description($asin){
$url = 'http://www.amazon.com/gp/aw/d/' . $asin . '?d=f&amp;pd=1';
$data = request_data($url);
$desc = '';

if ($data) {
    $dom = new DOMDocument();
    @$dom-&gt;loadHTML($data);
    $xpath = new DOMXPath($dom);
    if (preg_match('#dpItemFeaturesList#',$data)){
        $k = $xpath-&gt;query('//ul[@class="dpItemFeaturesList"]');
        foreach ($k as $c =&gt; $tot) {
            $desc .= $tot-&gt;nodeValue;
        }
    }
}
return $desc;
</code></pre>
