Calling Rust From PHP Without a Socket, Part 1: The Native Functions

Mon, 14 Sep 2026 20:40:00 -0700

ePHPm is a single Rust binary that embeds PHP. It carries its own KV store and its own SQLite-backed database in the same process. For a long time PHP code could only reach that KV store the same way it reaches Redis. It opened a TCP socket to the RESP listener ePHPm runs on localhost, encoded a command and waited for the reply. That works, and every PHP Redis client in existence already speaks it. But it is a strange thing to do when the hash map you’re talking to lives a few pointers away in the same address space.
