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.');
}

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', '');
?>

Anonymous ¶

from: http://www.ietf.org/rfc/rfc1635.txt

"What is Anonymous FTP?
"...
"Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address.  Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password.  Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services. "

So your code would be:
<?php
ftp_login('ftp.example.com', 'anonymous', 'user@example.com');
?>

If a blank password works, you might have a default password set in your php.ini

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);
