Thanks. Just what I was looking for. I used it to get at the RSS for my Google bookmarks:

$curlObj = curl_init();
curl_setopt($curlObj, CURLOPT_URL, “https://www.google.com/bookmarks/?output=rss”);
curl_setopt($curlObj, CURLOPT_USERPWD, “my_account_login_email:my_account_login_password”);
curl_setopt ($curlObj, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($curlObj);
echo $response;
curl_close($curlObj);
