parsing rss feed gives 500 internal server error

When i try to parse the google rss feed, i'm getting Network error: 500 internal server error in chrome and firefox developer tool. The first portion of downloading rss feed (with curl) works fine.

I found this example at: http://www.joevasquez.info/development/parsing-xml-feeds-with-php-rss-and-atom/#more-63

Can someone point out on what i'm doing wrong? thank you.

    $doc=new SimpleXmlElement($data,LIBXML_NOCDATA);

Ok, I got it to work. The error from the log:

Fatal error:  Call to undefined function  parserss()in /home1/aquinto1/public_html/belibook.com/curl/curl3.php on line 17

I cut and pasted function parserRSS before it was called and it works fine now.

The following is my modification:

$doc=new SimpleXmlElement($data,LIBXML_NOCDATA);

function parseRSS($xml){
    $cnt=count($xml->channel->item);
    for ($i=0;$i<$cnt;$i++){
        $url=$xml->channel->item[$i]->link;
        $title=$xml->channel->item[$i]->title;
        $desc=$xml->channel->item[$i]->description;
        echo '<a href="'.$url.'">'.$title.'</a>'.$desc.'<br>';
    }
}

if (isset($doc->channel)) parseRSS($doc);

Thank you both!

You forgot to close the bracket after the for loop.

for ($i=0;$i<$cnt;$i++){
     $url=$xml->channel->item[$i]->link;
     $title=$xml->channel->item[$i]->title;
     $desc=$xml->channel->item[$i]->description;
}
