This document discusses a PHP push notification system using MQTT protocol. It requires a Mosquitto MQTT server, Node.js, and Socket.io module to function. The client code connects to the Node.js server via Socket.io and subscribes to topics to listen for notifications. The Node.js code acts as a broker, connecting to the MQTT server and filtering websocket data based on topics. It listens for new notifications from MQTT and sends them to clients via websockets.

- 5. Client code 1. Connect to the node.js server through soket.io (L:5) 2. Subscribe to some topic(s) (L:10) 3. Listen to any notification for these topics (L:7-9)
- 6. Node.js code (1/3) 1. include the required modules (L:1-5) 2. Specify the web socket port (L:5) 3. Connect to the MQTT server (L:6)
- 7. Node.js code (2/3) 1. Listening to a successful socket connection (L:8) 1. Listening to a subscribing request from the client (L:9-13) 1. Filtering the web socket data based on the topics (L:11) 2. Listening to a notify request from the server (L:15-18)
- 8. Node.js code (3/3) 1. Listening to a new notification from the MQQT server (L:21) 1. Sent these notification through the web socket (L:23-25) 2. Listening to a successful connection with the MQTT server and sent a test notification every 5 seconds (L:29-33)
