PHP is NOT GPLd. It's got a license much like the apache license.

There is no linking clause. The basics of it are:

-- maintain copyright notice, whether distributed in binary or source.
-- Don't use the PHP name to endorse stuff.
-- anything with PHP in the name needs they permission
-- Must contain acknowledgement and the web site address
-- No one other than the PHP Group has the right to modify the terms
applicable to covered code created under this License.

That last one basically means you can't relicense it.
