Real time Messaging System using PHP and Firebase

Hi Friends, Here i am going to share source code of real time one on one messaging system for php application using Firebase Nosql Database. 

We all know php lacks in Real time communication and there are many application running in PHP based Server. So if you are interested to add real time messaging system in your app this is right example for you. We can also use Node.js to do this same kind of thing but for that we also need nodejs compatible server. 

Requiremets..

1 - PHP Application with Login System

2 - Firebase Project

3 - Firebase Admin SDK for PHP. 

      Note : I already added Admin SDK in my package so it is not required now but if you are interested to download it you can composer to download this via 

    composer require kreait/firebase-php ^4.18

To Create a Firebase Project visit https://console.firebase.google.com

1 - Click on Add Project

2 - Select Country and Language and so on. Once your project created click on the project app and then select web option out of 3 options

3 - then open your project and click on authentication

4 - Click on 'Sign in method' Tab and enable Email/Password Authentication

5 - In your firebase project app, on the left side there will be an icon of gear symble click on that and then click on project settings and click on Service Accouts and click on generate a new private key it will download a .json file and place it in your root directory

Now you are ready to download my package form github or you can clone it from this url https://github.com/Rizwan17/messenger.git

Steps to configure it

1 - Creat a Database in mysql(phpmyadmin) phpfirebase

CREATE DATABASE phpfirebase;

2- Create two tables users and chat_record

CREATE TABLE IF NOT EXISTS phpfirebase.users (

id INT(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,

    uuid VARCHAR(36) NOT NULL,

    username VARCHAR(50) NOT NULL,

    password VARCHAR(100) NOT NULL,

    UNIQUE KEY (uuid, username)

);

CREATE TABLE `chat_record`(

    `chat_uuid` VARCHAR(36) NOT NULL,

    `user_1_uuid` VARCHAR(36) NOT NULL,

    `user_2_uuid` VARCHAR(36) NOT NULL,

    UNIQUE KEY (chat_uuid)

);

ALTER TABLE users ADD fullname VARCHAR(100) NOT NULL AFTER uuid;

Now once again back to firebase console click on project overview and then click on web and copy the config code and paste it in inside the project folder phpfirebase/js/config.js file and now you can execute it
