Your promise is an empty one. It's very much MySQL, but I'll give it to
ya anyway: :-)

http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html

..... right there in the first several lines ...

"With ON DUPLICATE KEY UPDATE, the affected-rows value per row is 1 if
the row is inserted as a new row and 2 if an existing row is updated."

Php -> mysql_affected_rows($link)
