Code:
        foreach ($news as $item) {
            $url = sprintf(
                '%sindex.php?action=news&amp;newsid=%d&amp;newslang=%s',

                $item['id'],
                $item['lang']
            );

            $oLink = new Link($url, $this->config);

            if (isset($item['header'])) {
                $oLink->itemTitle = Strings::htmlentities($item['header']);
            }

            $output .= sprintf(
                '<h6%s><a id="news_%d" href="%s">%s <i aria-hidden="true" class="fa fa-caret-right"></i></a></h6>',

                Strings::htmlentities($item['header'])
            );

            $output .= sprintf('%s', $item['content']);

            if (strlen($item['link']) > 1) {

                    $item['target'],
                    Strings::htmlentities($item['linkTitle'])
