# Firebird PDO Driver (PDO_FIREBIRD)

## 简介

PDO_FIREBIRD is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to Firebird database.

## 安装

Use --with-pdo-firebird[=DIR] to install the PDO Firebird extension, where the optional `[=DIR]` is the Firebird base install directory.

    $ ./configure --with-pdo-firebird

## 预定义常量

下列常量由此驱动定义，且仅在扩展编译入 PHP 或在运行时动态载入时可用。另外，使用此驱动时，仅会使用这些驱动特定的常量。使用其他驱动的驱动特定的常量可能会导致不可预见的情况。如果代码可运行于多个驱动，PDO::getAttribute() 可被用于获取 `PDO_ATTR_DRIVER_NAME` 属性以检查驱动。

警告

The constants listed below have been DEPRECATED as of PHP 8.5.0. Use the corresponding Pdo\Firebird constants instead.

`PDO::FB_ATTR_DATE_FORMAT` (int)
