I dunno if unset() works on an object returned by mysql_fetch_object.

The double-dereference won't work in PHP3, only PHP4 (I think).

So what Cynic wrote will probably work.

But before we go too much further...

My gut is telling me that you should have been able to write some SQL to
make MySQL return only the records you want instead of getting a bunch of
extra ones and unsetting them after you've gotten them.

Databases have been optimized like crazy to do this sort of thing, and
unless there's some really esoteric PHP functionality to determine what to
throw out, you are way mo' betta off letting the database
filter/sort/search and return the right records.
