In this tutorial we will create a Update Data in XML File using PHP. This code will launch a bootstrap modal to update a specific XML data in the table. The code use file_put_contents() to save the XML data after the php loop assign the designate key value of POST data. This is a user-friendly kind of program feel free to modify it.

We will be using XML as a markup language that utilize in php as a HTML data. It is designed to store and transport data that can be manipulated within the local server.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html.

And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Lastly, this is the link for the jquery that i used in this tutorial https://jquery.com/.

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.
