Upgrade PHP 5.6 to 7.2
I am currently using PHP version PHP 5.6, and I want to upgrade to PHP version 7.2.21. Can you advise me on how to do this?
I gathered some resources to help you upgrade PHP 5.6 to 7.2.

The first link is from php.net and contains all of the changes with this upgrade path - including backward incompatible changes that I would recommend going over.
