I'm using if($mydata->DPRresponselocationaddress1 != "")
is this the same as if (!isset($mydata->DPRresponselocationaddress)) http://php.net/manual/en/function.isset.php or if (!empty($mydata->DPRresponselocationaddress)) http://php.net/manual/en/function.empty.phpor is there another function I have not learned yet? I don't really get the difference between isset and empty.
