In PHP 5.1, the SQLite extension also provides a driver for SQLite 2 databases; while it is not technically a part of the PDO_SQLITE driver, it behaves similarly, so it is documented alongside it. The SQLite 2 driver for PDO is provided primarily to make it easier to import legacy sqlite 2 database files into an application that uses the faster, more efficient sqlite 3 driver. As a result, the SQLite 2 driver is not as feature-rich as the SQLite 3 driver.
