After my previous article about creating PHP Progress Bar using flush() function and Javascript, I try to create another PHP progress bar using different approach. This time, I will not use flush() function. Instead, I will use Ajax method and jQuery to accomplish the task. Basically, in this new progress bar we will use jQuery Ajax library to trigger the long running process in the web server and then use jQuery Ajax library again to read the progress status and display it in the browser.

If you have a long running PHP script that executes many processes, you may need to inform user about the progress of the process when the script is still running and hasn't finished yet. Using progress bar can be the best option. We can combine the PHP flush() function, Javascript, and also CSS to create a nice progress bar.
