I am not a lawyer.  I think you have to say that before you say
anything about licenses.

The PHP license contains a sort of "advertising clause" (not quite
like the BSD advertising clause), which restricts derivative works
from using its name (perhaps among other things).  According to the
PHP license FAQ, this does not cover projects which *use* PHP.[1]  You
will need to determine if it covers things which *link* PHP.  If it
does not, you can write a PHP plugin which links both Pidgin and PHP
with no problem.



The laws that forbid the carrying of arms are laws [that have no remedy
for evils].  They disarm only those who are neither inclined nor
determined to commit crimes.
