Long story short, due to some health issues in the past few years, I am WAY behind in upgrading my server and PHP. Still running php 5.5.9!
Is there a script that can "lint" my code and tell me what is completely broken if I move to 8.1 and what can wait for a weekend and a pot of coffee? And if so, can that script be run on a 5.5.9 system or do I need to spin up a cheap VPS with 8.1 and run it against the code there?
Thanks for any advice.
