All right; this is a funny one ;-)
The patch-${php}-libxml.diff.orig patches is how it !ought! to work.
!!!BUT!!! 2 of the patches fails for some reason I can't discern.

So, in order to get it to compile, I've had to do:
#=> port clean --work "${phpV}"
#=> port extract "${phpV}"
#=> port -d patch "${phpV}"
#=> cd "$( port work "${phpV}" )/php*
#=> nano ext/soap/php_sdl.c
#=> nano ext/libxml/libxml.c
#=> port -d configure "${phpV}"
#=> port -d build "${phpV}"

$=> php80 -v
