# Firebird/Interbase Functions (PDO_FIREBIRD)

## Introduction

Warning

This extension is EXPERIMENTAL. The behaviour of this extension—including the names of its functions and any other documentation surrounding this extension—may change without notice in a future release of PHP. This extension should be used at your own risk.

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

## Predefined Constants

The constants below are defined by this driver, and will only be available when the extension has been either compiled into PHP or dynamically loaded at runtime. In addition, these driver-specific constants should only be used if you are using this driver. Using mysql-specific attributes with the postgres driver may result in unexpected behaviour. PDO::getAttribute() may be used to obtain the `PDO_ATTR_DRIVER_NAME` attribute to check the driver, if your code can run against multiple drivers.

`PDO::FB_ATTR_TIME_FORMAT` (integer)
