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.

If you receive an error while trying to write to a sqlite database (update, delete, drop):



Warning: PDO::query() [function.query]: SQLSTATE[HY000]: General error: 1 unable to open database



The folder that houses the database file must be writeable.
