This means the interbase extension isn't loaded into PHP.
You have two options:
1) compile PHP from source and include interbase support
2) compile interbase.so module and load it

In either case you'll need php sources. When you compile interbase.so,
make sure you load it:
a) at runtime use dl() function or
b) change the php.ini, and add
extension=interbase.so

.so files on Linux are equivalent to .dll files on Windows.

If you have trouble compiling the module, we can help you, but you must
write what version of Firebird you're using, since 1.5 requires some
manual changes to the source, AFAIK.
