PDOSQLITE

PDOSQLITE is the PDO (PHP Data Objects) driver that enables PHP applications to access SQLite databases using the PDO abstraction layer. It provides a uniform interface for connecting, querying, and managing SQLite data, while leveraging SQLite as the underlying database engine. PDOSQLITE supports both file-based SQLite databases and in-memory databases.

The driver is part of standard PHP distributions where the PDO extension and the sqlite3 extension are available. Activation typically involves enabling the pdo_sqlite extension in the PHP configuration (and the SQLite extension if required). A DSN such as sqlite:example.db or sqlite::memory: is used when creating a PDO instance. PDOSQLITE supports common PDO features including prepared statements, parameter binding, transactions, and various fetch modes. It exposes standard error handling via exceptions when PDO::ATTR_ERRMODE is set to PDO::ERRMODE_EXCEPTION.

SQLite via PDOSQLITE is well-suited for small to medium applications, embedded systems, or development environments where a lightweight, serverless database is desirable. It benefits from SQLite features such as zero-configuration, cross-platform support, and a small footprint, but is subject to SQLite’s concurrency model, which locks the database file during writes.

PDOSQLITE is maintained as part of PHP’s PDO ecosystem and relies on the SQLite library. Compatibility may vary with PHP versions and OS environments, so checking the official PHP documentation is advised.
