Fetch a Google Data feed using PHP & Curl

As a continuation from my last post, here's how you get a feed.

<?
// Note: this function assumes secure=0 AuthSub tokens
function getFeed($feedUri, $sessionToken) {
  $curl = curl_init($feedUri);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/atom+xml',
    'Authorization: AuthSub token="' . trim($sessionToken) . '"'
  ));
  $response = curl_exec($curl);

  if (!$response) {
    die('Error: ' . curl_error($curl) . "\n");
  }
  curl_close($curl);
  
  return $response;
}
?>
