Unserialize is used on arrays that have been serialized.

from the manual on count (http://www.php.net/manual/en/function.count.php):
If var is not an array or an object with implemented Countable interface, 1 will be returned.
and in your example $foo will be set to boolean false, so it cannot be "counted".
