Necklace\XxHash - PHP FFI bindings for libxxhash

This is an FFI binding of the libxxHash library from xxHash for PHP.

You're here because:

  • You want xxHash in PHP.
  • You don't want to install an extension.
  • You're fine with installing the xxhash package on your system to get libxxHash.
  • You want speed, or at least more speed than a pure PHP implementation of xxHash could get.

If so, you're in the right place.

Getting started

Setup

You will obviously need the xxHash package. In addition you will need libffi, and enable FFI for PHP (You will therefore need PHP version 7.4 or above). libxxhash needs to be v0.6.4 or above.

Here are some common ways to install:

  • Arch GNU/Linux: sudo pacman -S xxhash libffi
  • Debian / Ubundu: sudo apt install xxhash libffi
  • Fedora: sudo dnf install xxhash libffi
  • OpenSUSE: sudo zypper install xxhash libffi

PHP has to be compiled with the --with-ffi option, most distributions will have done this.

Locate the relevant php.ini file on your system and make sure these two lines are present, uncommented:

extension=ffi
ffi.enable=true

Then, simply add the bindings to your project:

composer require necklace/xxhash-ffi

Let me hash already!

Alright, alright. I know what you want, and I got what you need. You've got files, we got hashes:

Hash a file

<?php

use Necklace\XxHash\XxHash64;

$xxh = new XxHash64;

echo $xxh->hashFile('filename');

Hey man, I want the latest, fastest, and greatest!

This library supports the XXH3 algorithm, you can use this but beware; it's still labeled experimental : return values from this version are not comparable with other versions.

<?php

use Necklace\XxHash\Xxh3\XxHash64;

$xxh = new XxHash64;

echo $xxh->hashFile('filename');
