I basically need a unit conversion app using PHP. Just a simple app such as converting temperature, or length

Goal Design a simple, visually pleasant, PHP-based "app" that performs a useful function, namely, unit conversion Recommended Procedure: 1. Start from your Project 3 for the basic logic (which you will convert from JavaScript to PHP) and the look-and-feel (HTML, CSS, Bootstrap) (which you can reuse) Modify the example so that the conversion must take place on the server (PHP code), not on the client. 2. Test your app after every significant change/addition and document all meaningful changes in your report. Once you've reached a point where your app is complete and fully functional in the browser of your choice (Chrome, Firefox, Opera, or Safari), prepare the final package (single zip, all that is needed, and nothing else) Submit the final package via Canvas. 3. 4. 5. Minimum requirements: Your app must be your own work. If you use a site, textbook example or any other source as "inspiration" along the way, please make a note of it in your report. Your page should demonstrate a basic understanding of using forms and PHP to produce interactive, "data-driven" web pages. The conversion must take place on the server (PHP code), not on the client (JavaScript code from Project 3) Your page should demonstrate separation between presentation (CSS+Bootstrap), content (HTML5), backend processing (PHP), and interactive functionality
