如何打印网站名称或标签

Question

我有一个用于show rss feed的WordPress插件（超级rss阅读器） 我希望它显示网站的名称，在编码我认为它的名称标签， 我在插件中找到以下代码：

// Display the feed items
echo '<div class="srr-item ' . (($j%2 == 0) ? 'even' : 'odd') . '">';
echo '<div class="srr-title"><li><a href="' . $link . '"' . $newtab . ' title="Posted on ' . $date . '">' . $title . '</a></li></div>';
echo '<div class="srr-meta">';

我应该为此代码添加什么代码以用于Feed网站的e​​cho / print名称？

插件的完整代码如下：

<?php
/*
Plugin Name: Super RSS Reader
Plugin URI: http://www.aakashweb.com/wordpress-plugins/super-rss-reader/
Author URI: http://www.aakashweb.com/
Description: Super RSS Reader is jQuery based RSS reader widget, which displays the RSS feeds in the widget in an attractive way. It uses the jQuery easy ticker plugin to add a news ticker like effect to the RSS feeds. Multiple RSS feeds can be added for a single widget and they get separated in tabs. <a href="http://www.youtube.com/watch?v=02aOG_-98Tg" target="_blank" title="Super RSS Reader demo video">Check out the demo video</a>.
