Reproduce code:
---------------
In index.php I have: 

require_once('DB.php');
$db =& DB::connect( "mysql://username:password@localhost/server_attempts" );
if (DB::isError($db)) {
        echo "RE";
        exit();
}
$db->setFetchMode(DB_FETCHMODE_ASSOC);

$res=$db->query("INSERT INTO `table_name` (`date`, `ip`, `reverse-dns`, `user-agent`) VALUES (NOW(),?,?,?)", array($_SERVER['REMOTE_ADDR'], isset($_SERVER['REMOTE_HOST'])?$_SERVER['REMOTE_HOST']:"", $_SERVER['HTTP_USER_AGENT']));

$db->disconnect();
