How to run an php application without installing xampp on client system?

I'm a big fan of server2go. I've used it to deploy PHP applications on CD/DVD. It comes with MySQL and is relatively easy to configure. I've even replaced their splash screen with my own so no one knows I'm using it. It's donationware, but I was impressed enough to donate:

With this application, you don't have to install all that other stuff. It's self-contained in this executable and directory.

EDIT: To clarify, server2go does not install anything on the client machine. It runs as an exe only when you specifically want it to. When you click on the .exe file, it launches your PHP application in a browser window, then you can right-click on the server2go icon in the system tray and close it when you're done.

EDIT2: One gotcha: if you want to save data to the MySQL db on the client machine, you'll need to copy serve2go to a directory on the client machine or run it on a writable USB stick. If you run this application off CD/DVD, it will be able to read data from the database, but not write.

The better way is to use PHP Desktop Application. It will allow you to run your PHP Script like a Desktop application and you don't need to install Xampp or any other web server to run.

PHP Desktop Application

After downloading the .Zip file unzips it to any folder that you like. After unzipping, Go to the folder, and there you can see a folder "www". Delete all the files contained in it and move all your php script to it.

Once you moved all your files into it. Run the .Exe file named "PHP desktop-chrome"

It will open your PHP Script really like a Desktop Application.

This script doesn't require any kind of server software like Xampp, Wamp, Etc installed in your PC.

I really dont want to use any external software to render no database PHP pages so I did some digging and found that if you run php -S localhost:port in your working directory you basically start a server there.

S is a capital S and not s
