King PHP Extension

Systems-grade networking and infrastructure primitives for PHP

King turns PHP into a systems platform for transport-heavy, realtime, infrastructure-aware software. Instead of pushing critical networking, orchestration, discovery, storage, and control-plane work into sidecars, gateways, or glue layers, King keeps that work inside one native runtime that is directly available to PHP.

That changes what PHP can be used for. With King, PHP is no longer limited to short request handlers and thin application wrappers. It can own live sessions, streams, protocol state, routing decisions, telemetry, persistence, scaling signals, and cluster-facing workflows in one coherent runtime model.

The current line is beta. The repo-local baseline is green, the multi-backend object-store and control-plane surfaces are real, and the remaining closure work is now about narrower hardening, distributed-operating proof, and multi-node fleet behavior rather than paper subsystem claims.
