SQLite Functions (PDO_SQLITE)

简介

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.

Note:

PDO_SQLITE allows using strings apart from streams together with PDO::PARAM_LOB.

安装

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.

Note: Additional setup on Windows as of PHP 7.4.0

为了使此扩展生效, DLL 文件必须能在 Windows 系统的 PATH 指示的路径下找到。如何操作的信息,请参见题为“如何在 Windows 中将 PHP 目录加到 PATH 中”的FAQ。虽然将 DLL 文件从 PHP 文件夹复制到 Windows 系统目录也行,但不建议这样做。 此扩展需要下列文件在 PATH 路径中: libsqlite3.dll.
