Quick flurry of updates as Samba 4.6 finally went out of support earlier this month so no more patches, so quick deinstall of Samba46 and then install of Samba48 to get Samba back into support.
Update to PHP 7.1 was a bit more involved. Needed to update make.conf to amend the default_versions from 5.6 to 7.1 and then locate the port directories for mod_php56 and de-install. Quick build of mod_php71 to update that and then pkg delete php56 to remove all the extensions.
I have Kanboard and phpsysinfo installed, so a quick trip to their port directories to re-installed pulled in most of the PHP extensions needed, but oddly not php71-extensions, so on Apachectl Restart WordPress spewed up some Server 500 Errors. A quick check of the previous php extensions now installed versus the previous 56 variants thru up a few ports that had not been pulled back in. A quick re-build of those ports and another apachectl restart and all is well and Apache is now running PHP 7.1 happily.
