Updating PHP

[balanga]

I have an old WORDPRESS installation which uses numerous php56 modules. Is there a simple way to update all of them to php71?

For some reason I cannot install php72 modules. I get:-

pkg: No packages available to install matching 'php72-zip' have been found in the repositories

This is running in a FreeNAS jail, so that may be relevant.

I did see a thread - Thread 68359 which mentioned an upgrade process but referred to a Twitter thread, but I don't use Twitter.
