PHP extension for interfacing with Redis

This extension provides an API for communicating with Redis servers.

phpredis 3.0.0

This version of phpredis supports cluster and is intended for php versions
7.0.0 and higher. To compile cluster-enabled phpredis for older versions
of php, please use the 2.2.8 pecl package.

A huge thanks goes out to Sean DuBois for doing all the work required to get
phpredis working in php 7.0!
