PDO_SQLITE DSN — Connecting to SQLite databases
说明
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.
Note:
The sqlite2 driver is only available in PHP 5.1.x 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.
