PHP webserver not falling back to index.php when URL has an extension

[nicolas-grekas]

Description

Create an empty dir and put Hello in index.php.
run php -S localhost:8080 in that directory

go to http://localhost:8080/foo/bar, see Hello.
go to http://localhost:8080/foo/bar.baz, see a 404 from the builtin webserver instead of the expected Hello.

This must be a recent regression?
PHP 8.4 is not affected, but PHP 8.2.24 and 8.3.12 are (I didn't test earlier versions)

PHP Version

Interesting, I ran into something similar yesterday on 8.3.7 although my uri was something akin to /123/456.789

In PHP 8.3 and earlier, if the URL indicates a file (it has an extension) then the server assumes the request was for a file and so would return 404 when it couldn't be found. Developers are expected to use a router script if something more complicated is needed, such as URL rewriting.

That will change in 8.4, where it will automatically route such a request to the closest index file.

Oh so this is how it worked since always? Funny I notice only now :)
Another good reason to move to PHP 8.4! :)
