Detect broken anchors

[ondrejmirtes]

At https://phpstan.org/config-reference I have a broken anchor (/writing-php-code/phpdoc-types#type-aliases) but at https://phpstan.org/writing-php-code/phpdoc-types there's no anchor like that.

I'm using this action already at https://github.com/phpstan/phpstan/actions/workflows/website-links.yml but it doesn't detect this problem (there's no element with this ID).

It'd be nice if it detected this problem. Thank you.

This is definitely a usecase whose use I can understand well. Thanks for the suggestion.

Since you can't tell from the HTTP GET request to the URL alone if the anchor exists, since 200 - OK is invariably returned even though the anchor is not there, you would have to search for the anchor in the HTML.
