README

This extension allows for hashing via the xxHash algorithm.

Documentation for xxHash can be found at » http://code.google.com/p/xxhash/.

Purpose

This extension is maintained for educational purposes only. horde/xxhash used to tie into horde/lz4 for supporting the xxhash algorithm. Modern PHP 8 brings its own xxhash methods in core and horde/lz4 is going to be ported to this core functionality.

Making horde/xxhash compatible with latest PHP 8.x practices is a toy project and learning experience. It serves no practical purposes. I last contributed c code patches to PHP many years ago and mostly learned from Sara Golemon's seminal book on PHP Interals "Extending and Embedding PHP", published in 2006. I am also not the original author, neither of xxhash nor of horde/xxhash and in no way affiliated with the original PHP implementation.

You want to use this for some reason? Great! Let me know, I am curious!
