DStruct PHP Framework » \DBIterator

Wraps database result set functionality.

Gets results from PDO and turns them into arrays.
Works with statements and queries.
This also means that can use things like count() as PDO doesn't always automatically return a recordset count.
Also allows a different return modes.
