@gureedo I fixed it and clean some needless code for me

This line contains a bug:

list=$(git diff-tree --name-only -r $oldrev..$newrev | grep -e '.php' -e '.phtml')

It will find all files containing php in the name!
This is the right command string:

list=$(git diff-tree --name-only -r $oldrev..$newrev | grep -e '.php$' -e '.phtml$')

Actually I wouldn't recommend to use PHPCS for .phtml files.

@paunin thanks for Fix, now it works fine 👍

Something similar in python with a list to allow access: https://gist.github.com/adrianlzt/f30a4d7004671c5eea5b21ba6ef967d3
