(no version information, might be only in CVS)

PDO_SQLITE DSN -- Connecting to SQLite databases

## Description

The PDO_SQLITE Data Source Name (DSN) is composed of the following elements:

DSN prefix (SQLite 3)

  The DSN prefix is `sqlite:`.

  - To access a database on disk, append the absolute path to the DSN prefix.

  - To create a database in memory, append memory: to the DSN prefix.

DSN prefix (SQLite 2)

  The SQLite extension in PHP 5.1 provides a PDO driver that supports accessing and creating SQLite 2 databases. This enables you to access databases you may have created with the SQLite extension in previous versions of PHP.

  > 注: The sqlite2 driver is only available in PHP 5.1 if you have enabled both PDO and ext/sqlite. It is not currently available via PECL.

  The DSN prefix for connecting to SQLite 2 databases is `sqlite2:`.

  - To access a database on disk, append the absolute path to the DSN prefix.

  - To create a database in memory, append memory: to the DSN prefix.
