title: file_get_contents() failed to open stream:
body: <p>I'm trying to use <code>file_get_contents()</code> 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. <code>allow_url_fopen</code> is enabled in my <code>php.ini</code> file.</p>
  
  <p>Any idea what could be wrong?</p>
