`include` alias fails to redirect

[jefhar]

Affected Page URL

https://www.php.net/include/

Describe the bug

Every other function redirects or is an alias to the function page:
https://www.php.net/print is an alias to https://www.php.net/manual/en/function.print.php
https://www.php.net/ltrim is an alias to https://www.php.net/manual/en/function.ltrim.php

https://www.php.net/include/ is not an alias or redirect, but instead is a list of include files for the site.

Steps to reproduce

1. Go to https://www.php.net/include/

Expected behavior

I expected the same content as I would see on https://www.php.net/manual/en/function.include.php
