General Best Practices for encoding using php

Question

There are lots of questions about particular encoding problems but I could not find a good general best practices article. Basically my question(s) encompass:

1. What meta-tags should I put in all my .php/.html files if any?
2. What are good configuration settings for PHP.ini for supporting UTF-8. (As recommended by other articles here)
3. How would I handle AJAX calls to php with the proper encoding?
4. How would I save/load files to work well with the encoding settings of php?
5. Any common gotcha's to look out for?

Php has so many encoding options its just a forest to navigate and it seems one good example of these details done properly will keep a lot of people out of trouble. I found an excellent article here which is a great intro but lacks the specific php practices I am looking for. See also https://phpbestpractices.org/ which has some good general guidelines.
