What good is it you ask? You can use it to pull in information from any RSS feed and do what ever you want with the data. For example I use it to pull the RSS feed from my blog and display links to my latest posts on http://www.rewardchamp.com You can see it on the bottom of the page.

CakePHP makes this way to easy! First you need to download the MagpieRSS files from the link above and then extract to your vendors folder.

You need to put this line at the very top of your controller file you want to use RSS with. Before the class declaration

App::import('Vendor','Snoopy', array("file" => "magpierss/extlib/Snoopy.class.inc"));

Now inside a function you want create a new Snoopy object. I use Snoopy because I’m lazy … MagpieRSS is not constructed as Classes like CakePHP would like it to be … Snoopy is. Snoopy will return XML for you which you can make into an easily usable object with SimpleXMLElement. You can var_dump to see what exactly is in this object. You can figure out what to do from there.

$snoopy = new Snoopy();
$snoopy->fetch('http://www.solitechgmbh.com/your/feed/here');
$xml = new SimpleXMLElement($snoopy->results);
return $xml->channel->item;

Something like this will get you the title for example.

echo $item->title;

Happy coding!
