I discovered that my http.conf was actually not loading php7_mod, 
although the server displayed simple PHP files just fine and even 
supported simple debug code such as

<?php
$a="Hello";
print $1;
?>

With my limited knowledge of apache and php, I thought this meant my 
config was OK.

But after adding

    LoadModule php7_module lib/httpd/mod_php7.so

I got the following:

[root@login.finch php71] 586: apachectl -t
[Tue Aug 28 09:37:48.009689 2018] [php7:crit] [pid 11121:tid 
47450741299968] Apache is running a threaded MPM, but your PHP Module is 
not compiled to be threadsafe.  You need to recompile PHP.
AH00013: Pre-configuration failed

Recompiling php71 and ap-php with the maintainer-zts option fixed it.

So the question now is, should maintainer-zts be enabled by default, or 
must everyone who wants PHP support build from source?

Since I'm building my own packages, I can work around this in my pbulk 
settings, but it may still be a problem for others.
