What is a null value?

Help!

if ($dostyleid = NULL ) {

// my code if that matches up

}

Now, I don't know what a null value would be. I'm trying to tell it that if $dostyleid's value is empty, then do the code below...

This is the last little thing I must finish for some code of mine...help! :eek:

PHP Code:


		
			
if (!isset($dostyleid))

...meaning it hasn't been defined yet. Otherwise since there are no real data types in PHP that you can define, do:

PHP Code:


		
			
if ($dostyleid == false)
