&reftitle.install;

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

## Note to Win32/Win64 Users

&ext.windows.path.dll; `fbclient.dll,gds32.dll`

If you installed the Firebird/InterBase database server on the same machine PHP is running on, you will have this DLL already and `fbclient.dll,gds32.dll` (gds32.dll is generated from the installer for legacy applications) will already be in the `PATH`.
