How do I check if a variable is blank or not. I am returning data from a
MySQL database and if a field is empty I would like to do something
different.
I tried
if($field["Name"] == "") { do this }
else { do this }
It does not work right. Actually, at one point, it was working in the exact
opposite manner.
