using PHP 5.6 and PHP 7 on same web server

[Keith Smith]

Hi,

I need to test using PHP 5.6 and PHP 7. I have a computer that I will be 
configuring with as a test server.  I will make public facing 
periodically - just for testing and for a short time.  I want to use 
Ubuntu 16.4.

Is there any way to configure one server to give access to two different 
versions of PHP, possibly by some Apache config?

Thank you in advance for your insight.
