PDO_SQLITE DSN - Connecting to SQLite databases

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

	      o DSN prefix (SQLite 3)
		- The DSN prefix is sqlite:.

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

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

	      o 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:.

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

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