XLIV. InterBase functions

Introduction

InterBase is a popular database put out by Borland/Inprise. More information about InterBase is available at http://www.interbase.com/. Oh, by the way, InterBase just joined the open source movement!

Note: Full support for InterBase 6 was added in PHP 4.0.

This database uses a single quote (') character for escaping, a behavior similar to the Sybase database, add to your php.ini the following directive: 

magic_quotes_sybase = On

Requirements

Installation

To enable InterBase support configure PHP --with-interbase[=DIR], where DIR is the InterBase base install directory, which defaults to /usr/interbase.

Note to Win32 Users: In order to enable this module on a Windows environment, you must copy gds32.dll from the DLL folder of the PHP/Win32 binary package to the SYSTEM32 folder of your windows machine. (Ex: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM32). In case you installed the InterBase database server on the same machine PHP is running on, you will have this DLL already. Therfore you don't need to copy gds32.dll from the DLL folder.

Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.
