codeigniter 操作 Rss

I wrote a codeigniter library through which you can retrieve the rss feeds from xml file

Add the below code in Rss.php file and save the file in application library folder ,

Add the below code in your controller

 

<?php 
$this->load->libarary("rss");
$config["utl"]="rsslink";

$this->rss->initialize($config);

$result = $this->rss->getRss();

print_r($result);

?>
