Predis is a flexible and feature-complete PHP client library for the Redis key-value store.

Predis requires PHP >= 5.3 and it is entirely written in PHP.

It can be used without the need to build and install a native extension for the interpreter, making it also easier and faster to add new features which is great given how fast the development of Redis proceeds.

Speed up Predis

  • support HHVM >= 2.4.0
  • can be paired with a C extension phpiredis
