using PHP 5.6 and PHP 7 on same web server

[James Dugger]

Yeah manage them separately on different VM's or containers.  I try to spec
my VM's out as close to the production server's specs as possible to try
and minimize the "Well, it worked on my system" syndrome.  That means
potentially dozens of different settings and versions all down the LAMP
stack to and including the Linux operating system.  This could mean a lot
of different instances.  This is why I got familiar with Vagrant.  Or even
easier learn Docker and build containers.  They are fast and very efficient.
