I don't know how your other classes are arranged, but personally I'd build pagination into a class that provides raw data access, then inherit that for specific types of data like animals. Efficient pagination is too tightly coupled to the data source to be separate. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
