Strange problem with get_contents and twitter

Question

I made this function to check Twitter user credentials. It runs on two different web servers.

<?
function twitauth($username, $password){
if(@file_get_contents("http://".$username.":".$password."@twitter.com//account/verify_credentials.xml")){
    return "1";}
else {
    return "0";}

}

?>

It works fine on my web server. On the other hand, it ALWAYS returns 1! Even when the password is intentionally wrong.

What in the world can make one server do one thing and the other do something else?

Answer 1

I came up with an alternative solution.

<?
function twitauth($username, $password){
$xml = @simplexml_load_file("http://".$username.":".$password."@twitter.com/statuses/friends_timeline.xml");
$noway = $xml->error;
$errorcheck = "Could not authenticate you.";
if($noway == $errorcheck){
return "0";
} else {
return "1";
}

}

?>

?>
