Why isn't this code snippet working

[hubs]

I'm a total n00b. Could somebody tell me why this code doesn't work?

<?php

$uname = 'hubs';
                $pwd = 'bungle';
                $twitter_url = 'http://twitter.com/statuses/followers/
hubs.xml';
                $curl_handle = curl_init();
                curl_setopt($curl_handle,CURLOPT_URL,"$twitter_url");
                curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
                curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
                curl_setopt($curl_handle,CURLOPT_USERPWD,"$uname:
$pwd");
                $buffer = curl_exec($curl_handle);
                curl_close($curl_handle);
$file = "http://twitter.com/statuses/followers/hubs.xml";;
$xml = simplexml_load_file($file) or die ("Sorry Twitter is having
another freakout. Were unable to load the necessary
files!");
foreach ($xml->xpath('//name') as $name) {
    echo "$name/n";
}
?>
