Say I made a program using PHP that is like an organizer for appointments, and menu prices?

Author: Now say I wanted to remake this using new trendy software design. What code or language would I use to make this? It is old outdate PHP with bugs. I would like this to be fresh and new dated?. Any ideas or suggestions??
Try jQuery.

Are you saying you want to refurbish the website, or make the website available as client-side software?
To update the website, I would recommend using AJAX for automatic client-side calculations with javascript (which will obtain the results from server-side scripting in PHP)
If you want to write client-side software, I would recommend Delphi, as its database connectivity is considerably good, with C++ being a secondary option due to its flexibility in overall design.

Php is not "old" nor "outdated": your CODE is!
Most likely, it is your DESIGN that is outdated. (Oldish graphics etc)
And bugs are not "from php", but from YOUR coding…
Just re-do it from scratch.
Php is one of the most powerful languages for the web, if not the most, and is used daily by millions of (good) coders.
