Re: New extension for hardware accelerated crc32c

Just to follow up. The code for my PHP extension that makes use of hardware accelerated CRC32C instructions is here: https://github.com/google/php-crc32 I would love to get a pecl account, so I can publish this extension (to make it easy to download). thanks Andrew On Sat, 9 Mar 2019 at 22:36, Andrew Brampton <brampton@gmail.com> wrote: > Hi, > > I recently contributed a crc32c implementation to PHP's hash function > <https://github.com/php/php-src/pull/3913>.
