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.
PDO_SQLITE allows using strings apart from streams together with
The PDO_SQLITE PDO driver is enabled by default. To disable, --without-pdo-sqlite[=DIR] may be used, where the optional [=DIR] is the sqlite base install directory. As of PHP 7.4.0 » libsqlite ≥ 3.5.0 is required. Formerly, the bundled libsqlite could have been used instead, and was the default, if [=DIR] has been omitted.
