The relicensing of Xapian is very much not just about PHP - that's
simply an example of a current licensing incompatibility that
relicensing Xapian would address.
It would certainly be more helpful generally if PHP were licensed
compatibly with the GPL, but this isn't something I have time or
energy spare to attempt myself. If you (or somebody else) wants to talk
to the PHP developers please do.
