README

This repo is a derivative of jupyter-php-kernel.

Runtime architecture (PHP 8.5 compatible)

php-zmq/react/zmq are not used in PHP.

• The PHP kernel runs as a worker process over STDIN/STDOUT.
• A small Python bridge (bridge/jupyter_php_zmq_bridge.py) owns the Jupyter ZMQ sockets.
• Messages are forwarded between bridge and PHP worker as JSON lines with base64-encoded frames.

Requirements

• PHP >= 8.1
• Python 3
• pyzmq (pip install pyzmq)

Start Python ZMQ

python3 -m py_compile ./bridge/jupyter_php_zmq_bridge.py
