In this tutorial, you will learn how to build a shout box with PHP and jQuery, which allows visitors of your website to leave short comments to one another. Shouts will be stored on the server as files, no database like MySQL will be required. You are going to use two PHP libraries to make things easier – Flywheel for storing the shouts as json files and RelativeTime for creating human readable relative time stamps. You will be using Composer to install these libraries.
On the client side, you will be using plain jQuery code, and the Emoji One library, which is a free project and library for adding pretty emojis to web apps.
