PHP_CodeSniffer users: please read this important announcement: github.com/squizlabs/PHP_Cod… squizlabs/PHP_CodeSniffer is dead, long live PHPCSStandards/PHP_CodeSniffer! #phpcs #php

One example: sniffer is primarily about detection, the ability to fix automatically is a secondary concern. Fixer is the opposite, fixing is the entire focus. So something super simple like max line length is available in Sniffer. But adamantly rejected in Fixer because of how hard it would be to split a line of code reliably. Another one is risk tolerance. Sniffer will absolutely not alter anything that could possibly break code (like renaming a method) Fixer is willing to do it but labels the fix as risky. I really like both approaches for different reasons and in different contexts. Historically I’ve used sniffer but today I was trying to move to fixer and realized I probably need both.
