Thanks for the reply. It seems like using count() is the only way to test
for empty rowsets.
The question is more about iterators in general, since they can (almost) be
drop-in replacements for arrays.
I'm OK with using count(). I was just curious if it's possible to make an
object work with empty() and get expected results. Most of the developers on
my team have been used to using empty() with arrays and it can be confusing
why empty() won't work on a rowset. Maybe PHP needs a built-in IsEmpty
interface? :)

Calling empty() on a rowset (Zend_Db_Table_Rowset) always returns false,

for
an empty rowset?
You need to use count() or you could use the $rowset-count() method
directly. In the case of the Rowset class the count of returned rows is
held directly in a property so youre not iterating through each time its
called to get the value its simply returning.
If you actually need a boolean value you can cast it or you could extend
rowset and implemnt a method to do this and then call that.
Is there a particular reason you wanted to use empty (aside from
traditional
count/empty performance)?
