If the PHP's Licence is GPL incompatible you will not be able to
redistribute the code. In this case these routines will be like a
library, so any program that uses them must be also made GPL.

I think there are perl modules that have a GPL license, but they are not
linked with perl, they USE perl and programs that are made out with
these modules should be GPLed.

So if the "extension" we are talking of is only a module like perl
one's, than there is no problem to make it GPL (and use samba code), but
derived programs will have to be GPLed.

If the extension is _linked_ with the PHP interpreter code than that is
probably the problem.

Simo.
