If you are looking for an ORM that implements the Data Mapper paradigm rather than Active Record specifically, then I would strongly suggest that you take a look at GacelaPHP.
Gacela features:
- Data mapper
- Foreign key mapping
- Association mapping
- Dependent mapping
- Concrete table inheritance
- Query object
- Metadata mapping
- Lazy & eager loading
- Full Memcached support
Other ORM solutions are too bloated or have burdensome limitations when developing anything remotely complicated. Gacela resolves the limitations of the active record approach by implementing the Data Mapper Pattern while keeping bloat to a minimum by using PDO for all interactions with the database and Memcached.
