The simple answer is that isset is supposed to tell you if a var has
been created; a test for "" is looking for a value of a var. While
sometimes the results can be the same (and therefore confusing) that is
what the two provide. How you use them is dependent on your
understanding of PHP and the task before you.
if($mydata->DPRresponselocationaddress1 != "")
is this the same as
or is there another function I have not learned yet? I don't really get
the difference between isset and empty.
