Why? count() counts the number of objects in an array. Since we're giving it a scalar value, then it's one value. Would you expect count(array(false)) to give a zero or a false? How about count(0) versus count(1)?
You might be confusing false and null, which are not the same thing. False is a boolean number, null is an empty set. You'll note that count(null) gives a zero.
This is actually one of the cases where php is doing something logical. :)
