Using SSE in Updating Clients Changes in the Server
Briefly

It's been many days of Googling on how to use SSE in posting real-time updates to clients every time a change is made in the server like for example when a data is written to the database. Unfortunately, I didn't find any article that directly answers the problems I was facing when developing my little web application.
The main problem I came face to face was: how will I notify the web pages connected to my server when the server enters a new record or modify a record in the database? This could be happening directly in the server or another client sending data to the server.
Real-time updates in PHP can be facilitated by classes and functions like PushData, Puller, and Pusher, where data triggering and propagation mechanisms are defined for effective communication between server and clients through SSE.
