<?php $xml = simplexml_load_string($data, 'simplexmlelement', libxml_nocdata); ?>  <?php  $i = 0; foreach ($xml->channel->item $item) { $creator = $item->children('dc', true); echo '<h2>' . $item->title . '</h2>'; echo '<small>posted on '. date('l f d, y', strtotime($item->pubdate)) .' '.$creator.'</small> </p>'; echo '<p class="description">' . $item->description . '</p>'; if (++$i === 3) break; } ?>
