PHP version

Hey all,

Currently I’m running WP 4.2.6 with PHP 5.3.29.

I’m going to update WP to the latest stable version. I can also upgrade PHP to newer versions, even to PHP 7. What’s the best option to use in this case? Is PHP something I can use with the latest version of WP, or should I upgrade to PHP 5.6?

Thanks for the help!
