To suppress the PHP warning, just prepend the function with the error suppression character @. I'm usually against error suppression, but apparently some genius thought it was a good idea to really drive the point home that you have a bad login. Returning false wasn't enough?

if( ! @ftp_login( $connection, 'USERNAME', 'PASSWORD' ) ){
        die( 'Bad login, but no PHP warning thrown.');
}

If you want to remove the warning of a bad connection with handled error activated just add before :
set_error_handler("my_error_function", E_ALL & !E_WARNING);
and after the function :
set_error_handler("my_error_function", E_ALL);

Note that to make an anonymous ftp connection, you need to specify "anonymous" as the username and "" (empty string) as the password.

Example:
<?php
ftp_login
('ftp.example.com', 'anonymous', '');
?>
