Hi David,

IIRC, I think at that time, PHP5 was still fresh.  I remember a lot of
the open source projects were written with PHP4 compatibility.  I
don't remember if that particular project of mine was written for PHP4
or 5.  Any case, changes are good to an extent :).  I also did confirm
prior to your previous email, right after Gary showed me that quote
from the manual.  I'll have to remember that from now on :).
