We will be upgrading our PHP version from 7.1 to 7.2 soon. My understanding from the dev documentation is that core Moodle should be compatible for 3.4 and above. I am trying to figure out if there is a simple way to confirm that my additional plugins will be compatible with PHP 7.2, as well.
Is it safe for me to assume that a plugin that is compatible with Moodle 3.4+ is compatible with PHP 7.2? That would be the easiest thing for me to figure out, I reckon.
Otherwise, I guess I would either have to read several versions back of changelogs for each plugin and hope that the developer wrote something about PHP compatibility, or individually reach out to each developer, which would obviously be more time intensive for me.
All that said, of course we will be doing upgrades and testing in our development environment first. But, the more information, the better!
