I'm not so much experienced with compilation and installation of
various things in Linux, but this is how I made Xampp work with
support of Interbase:

1) You'll have to have installed xampp already
2) You'll have to install xampp-devel package (a must!!)
3) Get PHP5 source code and re-compile it with:
