Twitter API Help

[paulOr 0]

<?php
// Set username and password
$username = 'paulOr';
$password = '*******';
// The message you want to send

// The twitter API address
$url = 'http://twitter.com/statuses/update.xml';
// Alternative JSON version
// $url = 'http://twitter.com/statuses/update.json';
// Set up and execute the curl process
$curl_handle = curl_init();
curl_setopt($curl_handle, CURLOPT_URL, "$url");
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl_handle, CURLOPT_POST, 1);
curl_setopt($curl_handle, CURLOPT_USERPWD, "$username:$password");
$buffer = curl_exec($curl_handle);
curl_close($curl_handle);
// check for success or failure
if (empty($buffer)) {
	echo 'message';
} else {
	echo 'success';
}
?>

I simply want it to say 'succes' or 'failure' upon login, if the username was correct or not, iv tryed playing around and stuff, but cant seem to stop it from saying success :p I dont need it to tweet or anything like that, just to know if the authentification was done.

Can anyone help :(

have you examined the output of $buffer? does it have anything useful inside it? i may play around with this in a bit to see if i can figure anything out.
