phpredis/phpredis

PhpRedis is a PHP extension for communicating with Redis and compatible key-value stores.

The extension solves the problem of integrating Redis into PHP applications by providing a native API that communicates directly with Redis servers. It supports not only Redis but also Valkey, Dragonfly, and KeyDB, making it compatible with multiple Redis-compatible data stores. The extension is written in C, which allows it to offer performance benefits over pure PHP implementations by operating at a lower level within the PHP runtime.

Developers should choose this extension when building PHP applications that require caching, session storage, or other use cases where Redis provides value. It is particularly suited for projects where performance is important, since the C implementation avoids the overhead of pure PHP code. The extension supports Redis Cluster deployments, making it viable for applications that need to scale Redis horizontally. Anyone evaluating adoption should be aware that this is a native PHP extension, which means it requires compilation and installation on the server rather than being a simple package dependency.

The project receives substantial ongoing support through sponsored development, with a dedicated team actively maintaining the codebase and responding to issues and feature requests. The maintainers are accessible through multiple channels including GitHub issues and a dedicated Slack workspace for sponsors, indicating active engagement with the user community.
