amen, this behavior makes no sense even though sizeof() is an alias to
count().  sizeof('this') and sizeof('this long thing') are both 1, which
makes no sense.  I would go so far as to say a E_NOTICE is more
appropriate than E_STRICT - you should only be using count() for
arrays/objects.

Then Zend could remove the silly question from the cert example exam ;).
