One way to find out is to comment out the 

LoadModule php4_module        libexec/apache/libphp4.so
and
AddModule mod_php4.c

in httpd.conf and restart apache. I think you need to make sure this is
the source of the problem before getting too involved in trying to fix
it.

But then, I've found most apache/php errors actually derive from some
php extension and this can be traced by a process of elimination. It's
often then a dependency of the extension that has been updated, or
something.

Yes, but going to 4.11 should fix it as well.
