# SQLite Functions (PDO_SQLITE)

## Introducere

PDO_SQLITE is a driver that implements the PHP Data Objects (PDO) interface to enable access to SQLite 3 databases.

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.

> Notă:

> PDO_SQLITE allows using strings apart from streams together with `PDO::PARAM_LOB`.
