title: File-get-contents failed to open stream Unauthorized
body: <p>I am trying to use file_get_contents.I have made sure that allow_url_fopen is enabled in php.ini. As of now it is telling me:</p>
  
  <p>[function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 401 Unauthorized</p>
  
  <p>All I'm doing is the following, which I can access through browser without a problem. </p>
  
  <pre><code>$url=('http://site/@api/users/=john_smith@site.com/properties');
  $xmlString=file_get_contents($url);
  </code></pre>
  
  <p>I believe this is an authentication issue but not sure how I can supply the proper credentials from within the script itself. Any ideas would be greatly appreciated. </p>
