I have a script that looks for the variable to be NULL and then execute. Is
there a way for the script to look for anything or something in the variable

Ex:

Thank you for any help.

Hi,
Does 0(zero) really equate to null?
if( 0 == null )
{
echo 'true';
}
else echo 'false';
Result echo's: true
This can not be right, can it? I have never heard of such a thing. As
far as I recall from any language null is of no value equaling nothing?
So how can it equal 0?

Any help or explanation would be greatly appreciated.
In C the NULL macro is equal to 0. In PHP null is equivalent to 0. The
test will fail if you use === instead.
