It'd be nice to see a module/class/library/function that supported the good non-cryptographic hash functions which can be quite useful for some situations.
For example (particularly) CityHash, Jenkins, Murmur3, and Spooky.

They can be a nice performance boost for situations where you need to use lots of hashes and a cryptographic hash isn't needed.

Obviously you can just use sha for most things you could use a non-crypto hash for, but it'd still be nice to have them available, especially with the rise of 'big-data' type applications.

For reference, talks about selection, use case and comparisons, which might be interesting. 

Test script:

At least some good news : Murmur3 is supported as of PHP 8.1.0[1].
