Facebook Style Load Data in Timeline with PHP MySQL Ajax With Source Code

The Facebook Style Load Data in Timeline with PHP MySQL Ajax was developed using PHP, Ajax and MySQL Database as Back-End, If you’ve ever used a social media website like Facebook, you’ll know that when the page loads in the browser, it first loads the content loading placeholder and then loads the content on the web page. The Timeline feature of web development was used to present content on the web page. So, when the first page loads, the timeline skeleton loads first, with a loading placeholder, and then the actual page loads.

So, in this tutorial Auto Load More Data On Page Scroll In PHP, we’ll use PHP script to create a project content loading placeholder, and then use PHP script with Ajax, Mysql database, and jQuery to load data onto a web page. When we scroll down a web page to see more information, it first loads a timeline content loading placeholder using CSS and jQuery, and then it sends a request using Ajax.

In this Timeline Script Like Facebook also includes a downloadable Facebook Style Load Data in Timeline With Source Code for free, just find the downloadable source code below and click to start downloading.

To start creating this Facebook Style Load Data in Timeline, makes sure that you have sublime or any platform of PHP and MySQL installed in your computer.
