State of mhash?

Hi, I just noticed that the hash extension has a default-disabled --with-mhash option, that enables a couple of additional mhash_* functions. From what I was able to gather, mhash was an old extension that was superseded by hash, and hash provides a compatibility layer for mhash. Should these functions be deprecated? Should this compatibility layer be kept indefinitely? Regards, Nikita

The documentation[1] states for more than ten years now: | This extension is obsoleted by Hash. So I think actually deprecating these functions for PHP 8 is appropriate. [1] <https://www.php.net/manual/en/intro.mhash.php>

Given that the mhash compatability shim is literally just "map this function and args to that function and args", this one feels like a no-brainer. Anyone who can't upgrade because of /this/ change can literally just drop a single (short) PHP script into their program to polyfill those APIs. It would be a kindness for someone to provide that, and if nobody else does I may just drop a package on composer in the new few months. +1 -Sara
