Can someone double check me here, but I think I found a bug...
int 1
1 => int 2
2 => int 3
3 => int 4
4 => int 5
I think v is an array [1,2,3,4,5]

Subject: [PHP] is_null question
> Hi
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
Ahh...
and the winner is empty().
Thanks Christian for this elusive answer and everyone else for their input.

I need to check variables for blank values but it appears that is_null and
=="" return true if there is a space.
Any other suggestions?
Thanks

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
is usually enough.
For most uses it works fine, but if you really need to know wether or not
it's null, take one of the other suggestions.
For instance,

It's supported from 4.0.4, I think.

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
value for what I want.
