Came up while looking at #49373 / #49370 in stable30.

Summary

Using filter_var() should be safer / more likely to catch edge cases.

Also adds the url in the error output to help the operator track down the culprit faster.

I like this less, because it does not explicitely check the return of parse_url. It’s bad for static analysis also.

And $url in the single quoted string will not be interpolated.

Restructured the logic. Now we do it all. Plus we also check things even when not removing the web-root unlike master.

And $url in the single quoted string will not be interpolated.

🤦‍♂️ Fixed.
