//********************* CHANNEL **********************************

3-) نحوه استفاده مثال:
<ul id=rss>
<?php
include("includes/RSSReader.inc.php");
$rss = new RSSReader("http://yorsite/rss.aspx?id=0&Lang=fa");
$nn = $rss->getNumberOfNews();
for($i=0;$i<$nn;$i++){?>
<li><?php echo $rss->getItemTitle("rsslink",$i);?></li>
<?php }?>
</ul>
امیدوارم منظورت همین باشه و تونسته باشم کمکت کنم
