php mess

I was doing some housekeeping on one of my systems and using info.php it showed PHP Version 7.1.2, but when I ran pkg info all the php pkgs were php56... The initial confusion was resolved when I realised that info.php was info gathered from mod_php which was 71. Now what is the easiest way to sort out this mess? ie upgrade all the php56 modules to php71?
Make sure you set the correct default, the official default is 5.6. So any port that requires PHP will install version 5.6. Set this in /etc/make.conf:
Then remove all the PHP 5.6 modules and build the modules you need.
