file_get_contents() failed to open stream:
<p>I'm trying to use file_get_contents() to grab a twitter feed, however I'm getting the following warning: </p>

<pre><code>failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request
</code></pre>

<p>My code:</p>

<pre><code>$feed = 'http://twitter.com/statuses/user_timeline.rss?screen_name=google&amp;count=6';
$tweets = file_get_contents($feed);
</code></pre>

<p>I'm using google just for the sake of testing.  allow_url_fopen is enabled in my php.ini file.</p>

<p>Any idea what could be wrong?</p>
