Hi Everyone,
Here's my problem: I'd like to make the printing of some text dependent on
whether or not a variable is null. In the following example, when $row[1]
is null, what gets printed on the page is Email: . I'd like the
script to not print Email: if row[1] is null.
It looks like I
You can use:
if($row[1]){print Email:$row[1];}else{print ;}

I wanted to use is_null, but it isn't available in my version
(4.0B2)
What would be an equivalent? I'm fairly new to PHP.
I was using isset, but sometimes it is set to Null.
Null values are unacceptable, but zero is a perfectly acceptable

It doesn't tell you if a variable is actually null, but unless you
specifically need to know if it is actually "NULL", just testing for truth
