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? :) -- Hector On Thu, Oct 29, 2009 at 10:07 AM, prodigitalson <ant.cunning...@gmail.com>wrote: > > > Hector Virgen wrote: > > > > Calling empty() on a rowset (Zend_Db_Table_Rowset) always returns false, > > even if the rowset has zero rows.
