How to make phpcs find PHP8 errors in whole project directory?

Question

I am inside my project directory that has various files/folders and some have PHP8 fatal errors I have found when using the website (e.g. Fatal error: Uncaught Error: Non-static method), I am using the following command which I am expecting to show PHP8 compatibility errors:

php ./vendor/bin/phpcs . --extensions=php --standard=PHPCompatibility --runtime-set testVersion 8.0

However this is just returning 2 warnings that are for files inside /vendor directory, it doesn't seem to be finding the errors, I think this maybe because it's only searching through the vendor directory as I am using ./vendor/bin/phpcs what do I need to do to make it search through all PHP files in my project directory?

Answer 1

The second argument is the directory you want to crawl for errors. Currently you have that set to . which I assume would mean the current "vendor" directory. Try this:

php ./vendor/bin/phpcs /path/to/files/ --extensions=php --standard=PHPCompatibility --runtime-set testVersion 8.0
