I tried to have apache load modules for PHP 5.6 and 7 at the same time 
and got segfaults for my trouble.  It's probably also not possible to 
associate .php files with both versions of the module at the same time.

That said, there's probably a reasonable way to make this work.  Copy 
the apache config that's currently working to a separate directory, like 
/etc/httpd2/ .  Go into that dir and change the Listen port to something 
other than 80, like 81.  Change the PHP configuration such that it loads 
the PHP 7 module instead of the 5.6 module.  Change the ServerRoot to 
/etc/httpd2 .  Change the PidFile to run/httpd2.pid .  Fix the Log 
directives such that httpd2 isn't writing to the same log files as the 
first httpd.  Then you can start this alternate apache up with 
"apachectl -f /etc/httpd2/conf/httpd.conf", and view how everything 
looks in PHP 7 on http://servername:81/whatever.php .  (Or there'll be 
something I've forgotten, and it'll barf and write stuff to the error 
log....)

This is kind of a pain, but it should work properly for testing stuff.
